Changelog.md

0.9.13 (not yet released)

• Fixed my_init not properly exiting with a non-zero exit status when Ctrl-C is pressed.
• The GID of the docker_env group has been changed from 1000 to 8377, in order to avoid GID conflicts with any groups that you might want to introduce inside the container.
• The syslog-ng socket is now deleted before starting the syslog-ng daemon, to avoid the daemon from failing to start due to garbage on the filesystem. Thanks to Kingdon Barrett. Closes GH-129.
• Typo fixes by Arkadi Shishlov.

0.9.12 (release date: 2014-07-24)

• We now officially support nsenter as an alternative way to login to the container. With official support, we mean that we've provided extensive documentation on how to use nsenter, as well as related convenience tools. However, because nsenter has various issues, and for backward compatibility reasons, we still support SSH. Please refer to the README for details about nsenter, and what the pros and cons are compared to SSH.
  • The docker-bash tool has been modified to use nsenter instead of SSH.
  • What was previously the docker-bash tool, has now been renamed to docker-ssh. It now also works on a regular sh shell too, instead of bash specifically.
• Added a workaround for Docker's inability to modify /etc/hosts in the container (Docker bug 2267). Please refer to the README for details.
• Fixed an issue with SSH X11 forwarding. Thanks to Anatoly Bubenkov. Closes GH-105.
• The init system now prints its own log messages to stderr. Thanks to mephi42. Closes GH-106.

0.9.11 (release date: 2014-06-24)

• Introduced the docker-bash tool. This is a shortcut tool for logging into a container using SSH. Usage: docker-bash <CONTAINER ID>. See the README for details.
• Fixed various process waiting issues in my_init. Closes GH-27, GH-82 and GH-83. Thanks to André Luiz dos Santos and Paul Annesley.
• The ca-certificates package is now installed by default. This is because we include apt-transport-https, but Ubuntu 14.04 no longer installs ca-certificates by default anymore. Closes GH-73.
• Output print by Runit services are now redirected to the Docker logs instead of to proctitle. Thanks to Paul Annesley.
• Container environment variables are now made available to SSH root shells. If you login with SSH through a non-root account, then container environment variables are only made available if that user is a member of the docker_env group. Thanks to Bernard Potocki.
• add-apt-repository is now installed by default. Closes GH-74.
• Various minor fixes and contributions thanks to yebyen, John Eckhart, Christoffer Sawicki and Brant Fitzsimmons.

0.9.10 (release date: 2014-05-12)

• Upgraded to Ubuntu 14.04 (Trusty). We will no longer release images based on 12.04. Thanks to contributions by mpeterson, Paul Jimenez, Santiago M. Mola and Kingdon Barrett.

• Fixed a problem with my_init not correctly passing child processes' exit status. Fixes GH-45.

• When reading environment variables from /etc/container_environment, the trailing newline (if any) is ignored. This makes commands like this work, without unintentially adding a newline to the environment variable value:

   echo my_value > /etc/container_environment/FOO
  

  If you intended on adding a newline to the value, ensure you have two trailing newlines:

   echo -e "my_value\n" > /etc/container_environment/FOO
  

• It was not possible to use docker run -e to override environment variables defined in /etc/container_environment. This has been fixed (GH-52). Thanks to Stuart Campbell for reporting this bug.

0.9.9 (release date: 2014-03-25)

• Fixed a problem with rssh. (Slawomir Chodnicki)
• The INITRD environment variable is now set in the container by default. This prevents updates to the initramfs from running grub or lilo.
• The ischroot tool in Ubuntu has been modified to always return true. This prevents updates to the initscripts package from breaking /dev/shm.
• Various minor bug fixes, improvements and typo corrections. (Felix Hummel, Laurent Sarrazin, Dung Quang, Amir Gur)

0.9.8 (release date: 2014-02-26)

• Fixed a regression in my_init which causes it to delete environment variables passed from Docker.
• Fixed my_init not properly forcing Runit to shut down if Runit appears to refuse to respond to SIGTERM.

0.9.7 (release date: 2014-02-25)

• Improved and fixed bugs in my_init (Thomas LÉVEIL):
  • It is now possible to enable the insecure key by passing --enable-insecure-key to my_init. This allows users to easily enable the insecure key for convenience reasons, without having the insecure key enabled permanently in the image.
  • my_init now exports environment variables to the directory /etc/container_environment and to the files /etc/container_environment.sh, /etc/container_environment.json. This allows all applications to query what the original environment variables were. It is also possible to change the environment variables in my_init by modifying /etc/container_environment. More information can be found in the README, section "Environment variables".
  • Fixed a bug that causes it not to print messages to stdout when there is no pseudo terminal. This is because Python buffers stdout by default.
  • Fixed an incorrectly printed message.
• The insecure key is now also available in PuTTY format. (Thomas LÉVEIL)
• Fixed enable_insecure_key removing already installed SSH keys. (Thomas LÉVEIL)
• The baseimage-docker image no longer EXPOSEs any ports by default. The EXPOSE entries were originally there to enable some default guest-to-host port forwarding entries, but in recent Docker versions they changed the meaning of EXPOSE, and now EXPOSE is used for linking containers. As such, we no longer have a reason to EXPOSE any ports by default. Fixes GH-15.
• Fixed syslog-ng not being able to start because of a missing afsql module. Fixes the issue described in pull request 7.
• Removed some default Ubuntu cron jobs which are not useful in Docker containers.
• Added the logrotate service. Fixes GH-22.
• Fixed some warnings in /etc/my_init.d/00_regen_ssh_host_keys.sh.
• Fixed some typos in the documentation. (Dr Nic Williams, Tomer Cohen)

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 now 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
