+Hey, thanks for wanting to contribute to baseimage-docker. :)
+
+If you have a question, please use the [discussion forum](https://groups.google.com/d/forum/passenger-docker). The Github issue tracker is only for **bug reports and feature requests**.
+
+If you want to develop baseimage-docker, use the Vagrantfile in the repository. It will setup an Ubuntu VM with Docker installed in it. Use the Makefile to build the Docker image.
+
+All development happens on the `next` branch. The `master` branch is supposed to point to the latest stable release, because users read documentation from the `master` branch.

-## 0.9.6 (release date: 2014-02-17)
-
- * Fixed a bug in `my_init`: child processes that have been adopted during execution of init scripts are now properly reaped.
- * Much improved `my_init`:
-   * It is now possible to run and watch a custom command, possibly in addition to running runit. See "Running a one-shot command in the container" in the README.
-   * It is now possible to skip running startup files such as /etc/rc.local.
-   * Shutdown is not much faster. It previously took a few seconds, but it is now almost instantaneous.
-   * It ensures that all processes in the container are properly shut down with SIGTERM, even those that are not direct child processes of `my_init`.
- * `setuser` now also sets auxilliary groups, as well as more environment variables such as `USER` and `UID`.
-
-## 0.9.5 (release date: 2014-02-06)
-
- * Environment variables are now no longer reset by runit. This is achieved by running `runsvdir` directly instead of through Debian's `runsvdir-start`.
- * The insecure SSH key is now disabled by default. You have to explicitly opt-in to use it.
-
-## 0.9.4 (release date: 2014-02-03)
-
- * Fixed syslog-ng startup problem.
-
-## 0.9.3 (release date: 2014-01-31)
-
- * It looks like Docker changed their Ubuntu 12.04 base image, thereby breaking our Dockerfile. This has been fixed.
- * The init system (`/sbin/my_init`) now supports running scripts during startup. You can put startup scripts `/etc/my_init.d`. `/etc/rc.local` is also run during startup.
- * To improve security, the base image no longer contains pregenerated SSH host keys. Instead, users of the base image are encouraged to regenerate one in their Dockerfile. If the user does not do that, then random SSH host keys are generated during container boot.
-
-## 0.9.2 (release date: 2013-12-11)
-
- * Fixed SFTP support. Thanks Joris van de Donk!
-
-## 0.9.1 (release date: 2013-11-12)
-
- * Improved init process script (`/sbin/my_init`): it now handles shutdown correctly. Previously, `docker stop` would not have any effect on `my_init`, causing the whole container to be killed with SIGKILL. The new init process script gracefully shuts down all runit services, then exits.
-
-## 0.9.0 (release date: 2013-11-12)
-
- * Initial release

-Ubuntu is not designed to be run inside docker. Its init system, Upstart, assumes that it's running on either real hardware or virtualized hardware, but not inside a Docker container. But inside a container you don't want a full system anyway, you want a minimal system. But configuring that minimal system for use within a container has many strange corner cases that are hard to get right if you are not intimately familiar with the Unix system model. This can cause a lot of strange problems.

 <a name="docker_single_process"></a>
 ### Wait, I thought Docker is about running a single process in a container?
 
-Absolutely not true. Docker runs fine with multiple processes in a container. In fact, there is no technical reason why you should limit yourself to one process - it only makes things harder for you and breaks all kinds of essential system functionality, e.g. syslog.
+The Docker developers advocate the philosophy of running a single *logical service* per container. A logical service can consist of multiple OS processes.
 
-Baseimage-docker *encourages* multiple processes through the use of runit.
+Baseimage-docker only advocates running multiple OS processes inside a single container. We believe this makes sense because at the very least it would solve [the PID 1 problem](http://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/) and the "syslog blackhole" problem. By running multiple processes, we solve very real Unix OS-level problems, with minimal overhead and without turning the container into multiple logical services.
+
+Splitting your logical service into multiple OS processes also makes sense from a security standpoint. By running processes as different users, you can limit the impact of vulnerabilities. Baseimage-docker provides tools to encourage running processes as different users, e.g. the `setuser` tool.
+
+Do we advocate running multiple *logical services* in a single container? Not necessarily, but we do not prohibit it either. While the Docker developers are very opinionated and have very rigid philosophies about how containers *should* be built, Baseimage-docker is completely unopinionated. We believe in freedom: sometimes it makes sense to run multiple services in a single container, and sometimes it doesn't. It is up to you to decide what makes sense, not the Docker developers.
+
+<a name="fat_containers"></a>
+### Does Baseimage-docker advocate "fat containers" or "treating containers as VMs"?
+
+There are people who think that Baseimage-docker advocates treating containers as VMs because Baseimage-docker advocates the use of multiple processes. Therefore, they also think that Baseimage-docker does not follow the Docker philosophy. Neither of these impressions are true.
+
+The Docker developers advocate running a single *logical service* inside a single container. But we are not disputing that. Baseimage-docker advocates running multiple *OS processes* inside a single container, and a single logical service can consist of multiple OS processes.
+
+It follows that Baseimage-docker also does not deny the Docker philosophy. In fact, many of the modifications we introduce are explicitly in line with the Docker philosophy. For example, using environment variables to pass parameters to containers is very much the "Docker way", and providing [a mechanism to easily work with environment variables](#environment_variables) in the presence of multiple processes that may run as different users.

+as a web server.
 
-The shell script must be called `run`, must be executable, and is to be placed in the directory `/etc/service/<NAME>`.

-    #!/bin/sh
-    # `/sbin/setuser memcache` runs the given command as the user `memcache`.
-    # If you omit that part, the command will be run as root.
-    exec /sbin/setuser memcache /usr/bin/memcached >>/var/log/memcached.log 2>&1
+**Be certain that you do not start your container using interactive mode
+(`-it`) with another command, as `runit` must be the first process to run. If you do this, your runit service directories won't be started. For instance, `docker run -it <name> bash` will bring you to bash in your container, but you'll lose all your daemons.**
 
-    ### In Dockerfile:
-    RUN mkdir /etc/service/memcached
-    ADD memcached.sh /etc/service/memcached/run
+Here's an example showing you how a `runit` service directory can be
+made for a `memcached` server.
 
-Note that the shell script must run the daemon **without letting it daemonize/fork it**. Usually, daemons provide a command line flag or a config file option for that.
+In `memcached.sh`, or whatever you choose to name your file (make sure

+```bash
+#!/bin/sh
+# `/sbin/setuser memcache` runs the given command as the user `memcache`.
+# If you omit that part, the command will be run as root.
+exec /sbin/setuser memcache /usr/bin/memcached >>/var/log/memcached.log 2>&1

+In an accompanying `Dockerfile`:
+
+```Dockerfile
+RUN mkdir /etc/service/memcached
+COPY memcached.sh /etc/service/memcached/run
+RUN chmod +x /etc/service/memcached/run
+```
+A given shell script must run **without daemonizing or forking itself**;
+this is because `runit` will start and restart your script on its own.
+Usually, daemons provide a command line flag or a config file option for
+preventing such behavior - essentially, you just want your script to run
+in the foreground, not the background.

 ### Running scripts during container startup
 
 The baseimage-docker init system, `/sbin/my_init`, runs the following scripts during startup, in the following order:
 
- * All executable scripts in `/etc/my_init.d`, if this directory exists. The scripts are run during in lexicographic order.
+ * All executable scripts in `/etc/my_init.d`, if this directory exists. The scripts are run in lexicographic order.
  * The script `/etc/rc.local`, if this file exists.
 
 All scripts must exit correctly, e.g. with exit code 0. If any script exits with a non-zero exit code, the booting will fail.
 
+**Important note:** If you are executing the container in interactive mode (i.e. when you run a container with `-it`), rather than daemon mode, you are sending stdout directly to the terminal (`-i` interactive `-t` terminal). If you are not calling `/sbin/my_init` in your run declaration, `/sbin/my_init` will not be executed, therefore your scripts will not be called during container startup.
+
 The following example shows how you can add a startup script. This script simply logs the time of boot to the file /tmp/boottime.txt.
 
-    ### In logtime.sh (make sure this file is chmod +x):
+In `logtime.sh`:
+
     #!/bin/sh
     date > /tmp/boottime.txt
 
-    ### In Dockerfile:
+In `Dockerfile`:
+
     RUN mkdir -p /etc/my_init.d
-    ADD logtime.sh /etc/my_init.d/logtime.sh
+    COPY logtime.sh /etc/my_init.d/logtime.sh
+    RUN chmod +x /etc/my_init.d/logtime.sh
+
+<a name="environment_variables"></a>
+
+#### Shutting down your process
+
+`/sbin/my_init` handles termination of children processes at shutdown. When it receives a SIGTERM
+it will pass the signal onto the child processes for correct shutdown. If your process is started with
+a shell script, make sure you `exec` the actual process, otherwise the shell will receive the signal
+and not your process.
+
+`/sbin/my_init` will terminate processes after a 5 second timeout. This can be adjusted by setting
+environment variables:
+
+    # Give children processes 5 minutes to timeout
+    ENV KILL_PROCESS_TIMEOUT=300
+    # Give all other processes (such as those which have been forked) 5 minutes to timeout
+    ENV KILL_ALL_PROCESSES_TIMEOUT=300
+
+Note: Prior to 0.11.1, the default values for `KILL_PROCESS_TIMEOUT` and `KILL_ALL_PROCESSES_TIMEOUT`
+were 5 seconds. In version 0.11.1+ the default process timeout has been adjusted to 30 seconds to
+allow more time for containers to terminate gracefully. The default timeout of your container runtime
+may supersede this setting, for example Docker currently applies a [10s timeout](https://docs.docker.com/engine/reference/commandline/stop/#options)
+by default before sending SIGKILL, upon `docker stop` or receiving SIGTERM.
+
+### Environment variables
+
+If you use `/sbin/my_init` as the main container command, then any environment variables set with `docker run --env` or with the `ENV` command in the Dockerfile, will be picked up by `my_init`. These variables will also be passed to all child processes, including `/etc/my_init.d` startup scripts, Runit and Runit-managed services. There are however a few caveats you should be aware of:
+
+ * Environment variables on Unix are inherited on a per-process basis. This means that it is generally not possible for a child process to change the environment variables of other processes.
+ * Because of the aforementioned point, there is no good central place for defining environment variables for all applications and services. Debian has the `/etc/environment` file but it only works in some situations.
+ * Some services change environment variables for child processes. Nginx is one such example: it removes all environment variables unless you explicitly instruct it to retain them through the `env` configuration option. If you host any applications on Nginx (e.g. using the [passenger-docker](https://github.com/phusion/passenger-docker) image, or using Phusion Passenger in your own image) then they will not see the environment variables that were originally passed by Docker.
+ * We ignore HOME, SHELL, USER and a bunch of other environment variables on purpose, because _not_ ignoring them will break multi-user containers. See https://github.com/phusion/baseimage-docker/pull/86 -- A workaround for setting the `HOME` environment variable looks like this: `RUN echo /root > /etc/container_environment/HOME`. See https://github.com/phusion/baseimage-docker/issues/119
+
+`my_init` provides a solution for all these caveats.
+
+<a name="envvar_central_definition"></a>
+#### Centrally defining your own environment variables
+
+During startup, before running any [startup scripts](#running_startup_scripts), `my_init` imports environment variables from the directory `/etc/container_environment`. This directory contains files named after the environment variable names. The file contents contain the environment variable values. This directory is therefore a good place to centrally define your own environment variables, which will be inherited by all startup scripts and Runit services.
+
+For example, here's how you can define an environment variable from your Dockerfile:
+
+    RUN echo Apachai Hopachai > /etc/container_environment/MY_NAME
+
+You can verify that it works, as follows:
+
+    $ docker run -t -i <YOUR_NAME_IMAGE> /sbin/my_init -- bash -l
+    ...
+    *** Running bash -l...
+    # echo $MY_NAME
+    Apachai Hopachai
+
+**Handling newlines**
+
+If you've looked carefully, you'll notice that the 'echo' command actually prints a newline. Why does $MY_NAME not contain a newline then? It's because `my_init` strips the trailing newline. If you intended on the value having a newline, you should add *another* newline, like this:
+
+    RUN echo -e "Apachai Hopachai\n" > /etc/container_environment/MY_NAME
+
+<a name="envvar_dumps"></a>
+#### Environment variable dumps
+
+While the previously mentioned mechanism is good for centrally defining environment variables, itself does not prevent services (e.g. Nginx) from changing and resetting environment variables from child processes. However, the `my_init` mechanism does make it easy for you to query what the original environment variables are.
+
+During startup, right after importing environment variables from `/etc/container_environment`, `my_init` will dump all its environment variables (that is, all variables imported from `container_environment`, as well as all variables it picked up from `docker run --env`) to the following locations, in the following formats:
+
+ * `/etc/container_environment`
+ * `/etc/container_environment.sh` - a dump of the environment variables in Bash format. You can source the file directly from a Bash shell script.
+ * `/etc/container_environment.json` - a dump of the environment variables in JSON format.
+
+The multiple formats make it easy for you to query the original environment variables no matter which language your scripts/apps are written in.
+
+Here is an example shell session showing you how the dumps look like:
+
+    $ docker run -t -i \
+      --env FOO=bar --env HELLO='my beautiful world' \
+      phusion/baseimage:<VERSION> /sbin/my_init -- \
+      bash -l
+    ...
+    *** Running bash -l...
+    # ls /etc/container_environment
+    FOO  HELLO  HOME  HOSTNAME  PATH  TERM  container
+    # cat /etc/container_environment/HELLO; echo
+    my beautiful world
+    # cat /etc/container_environment.json; echo
+    {"TERM": "xterm", "container": "lxc", "HOSTNAME": "f45449f06950", "HOME": "/root", "PATH": "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "FOO": "bar", "HELLO": "my beautiful world"}
+    # source /etc/container_environment.sh
+    # echo $HELLO
+    my beautiful world
+
+<a name="modifying_envvars"></a>
+#### Modifying environment variables
+
+It is even possible to modify the environment variables in `my_init` (and therefore the environment variables in all child processes that are spawned after that point in time), by altering the files in `/etc/container_environment`. After each time `my_init` runs a [startup script](#running_startup_scripts), it resets its own environment variables to the state in `/etc/container_environment`, and re-dumps the new environment variables to `container_environment.sh` and `container_environment.json`.
+
+But note that:
+
+ * modifying `container_environment.sh` and `container_environment.json` has no effect.
+ * Runit services cannot modify the environment like that. `my_init` only activates changes in `/etc/container_environment` when running startup scripts.
+
+<a name="envvar_security"></a>
+#### Security
+
+Because environment variables can potentially contain sensitive information, `/etc/container_environment` and its Bash and JSON dumps are by default owned by root, and accessible only to the `docker_env` group (so that any user added this group will have these variables automatically loaded).
+
+If you are sure that your environment variables don't contain sensitive data, then you can also relax the permissions on that directory and those files by making them world-readable:
+
+    RUN chmod 755 /etc/container_environment
+    RUN chmod 644 /etc/container_environment.sh /etc/container_environment.json
+
+<a name="logging"></a>
+### System logging
+
+Baseimage-docker uses syslog-ng to provide a syslog facility to the container. Syslog-ng is not managed as an runit service (see below). Syslog messages are forwarded to the console.
+
+#### Log startup/shutdown sequence
+In order to ensure that all application log messages are captured by syslog-ng, syslog-ng is started separately before the runit supervisor process, and shutdown after runit exits. This uses the [startup script facility](#running_startup_scripts) provided by this image. This avoids a race condition which would exist if syslog-ng were managed as an runit service, where runit kills syslog-ng in parallel with the container's other services, causing log messages to be dropped during a graceful shutdown if syslog-ng exits while logs are still being produced by other services.
+
+<a name="upgrading_os"></a>
+### Upgrading the operating system inside the container
+
+Baseimage-docker images contain an Ubuntu operating system (see OS version at [Overview](#overview)). You may want to update this OS from time to time, for example to pull in the latest security updates. OpenSSL is a notorious example. Vulnerabilities are discovered in OpenSSL on a regular basis, so you should keep OpenSSL up-to-date as much as you can.
+
+While we release Baseimage-docker images with the latest OS updates from time to time, you do not have to rely on us. You can update the OS inside Baseimage-docker images yourself, and it is recommended that you do this instead of waiting for us.
+
+To upgrade the OS in the image, run this in your Dockerfile:
+
+    RUN apt-get update && apt-get upgrade -y -o Dpkg::Options::="--force-confold"

+ * Cons
+   * If the `docker exec` process on the host is terminated by a signal (e.g. with the `kill` command or even with Ctrl-C), then the command that is executed by `docker exec` is *not* killed and cleaned up. You will either have to do that manually, or you have to run `docker exec` with `-t -i`.
+   * Requires privileges on the Docker host to be able to access the Docker daemon. Note that anybody who can access the Docker daemon effectively has root access.

+
+<a name="enabling_ssh"></a>
+#### Enabling SSH
+
+Baseimage-docker disables the SSH server by default. Add the following to your Dockerfile to enable it:
+
+    RUN rm -f /etc/service/sshd/down
+
+    # Regenerate SSH host keys. baseimage-docker does not contain any, so you
+    # have to do that yourself. You may also comment out this instruction; the
+    # init system will auto-generate one during boot.
+    RUN /etc/my_init.d/00_regen_ssh_host_keys.sh
+
+Alternatively, to enable sshd only for a single instance of your container, create a folder with a [startup script](#running_startup_scripts).  The contents of that should be
+
+    ### In myfolder/enable_ssh.sh (make sure this file is chmod +x):
+    #!/bin/sh
+    rm -f /etc/service/sshd/down
+    ssh-keygen -P "" -t dsa -f /etc/ssh/ssh_host_dsa_key
+
+Then, you can start your container with
+
+    docker run -d -v `pwd`/myfolder:/etc/my_init.d my/dockerimage
+
+This will initialize sshd on container boot.  You can then access it with the insecure key as below, or using the methods to add a secure key.  Further, you can publish the port to your machine with -p 2222:22 allowing you to ssh to 127.0.0.1:2222 instead of looking up the ip address of the container.

+<a name="ssh_keys"></a>
+#### About SSH keys
+
+First, you must ensure that you have the right SSH keys installed inside the container. By default, no keys are installed, so nobody can login. For convenience reasons, we provide [a pregenerated, insecure key](https://github.com/phusion/baseimage-docker/blob/master/image/services/sshd/keys/insecure_key) [(PuTTY format)](https://github.com/phusion/baseimage-docker/blob/master/image/services/sshd/keys/insecure_key.ppk) that you can easily enable.

+#### Using the insecure key for one container only
+
+You can temporarily enable the insecure key for one container only. This means that the insecure key is installed at container boot. If you `docker stop` and `docker start` the container, the insecure key will still be there, but if you use `docker run` to start a new container then that container will not contain the insecure key.

Do this at build time by passing a variable in with `--build-arg`  as in `docker build --build-arg DISABLE_SYSLOG=1 image/`, or you may set the variable in `image/Dockerfile` with an ENV setting above the RUN directive.
+
+These represent build-time configuration, so setting them in the shell env at build-time [will not have any effect](https://github.com/phusion/baseimage-docker/issues/459#issuecomment-439177442).  Setting them in child images' Dockerfiles will also not have any effect.)
+
+You can also set them directly as shown in the following example, to prevent `sshd` from being installed into your image, set `1` to the `DISABLE_SSH` variable in the `./image/buildconfig` file.
+
+    ### In ./image/buildconfig
+    # ...
+    # Default services
+    # Set 1 to the service you want to disable
+    export DISABLE_SYSLOG=0
+    export DISABLE_SSH=1
+    export DISABLE_CRON=0
+
+Then you can proceed with `make build` command.
