Vagga 0.8.0

Release Date:22.09.2017
  • [breaking] !Copy now resets file modification time to unixtime 1, this improves reproducibility of containers
  • Added !YarnDependencies command (still a bit experimental)
  • Added !GitDescribe command
  • Added rules to !Copy command
  • Added sha256 option to !Download buildd step
  • Added allow-pre-releases option to PipConfig
  • Added disable-auto-clean setting (mostly useful for CI)
  • The /etc/resolv.conf and /etc/hosts are mounted into container instead of copying/owerwriting (this is potentially a breaking issue)
  • Default alpine mirror is now dl-cdn.alpinelinux.org instead of random

Vagga 0.7.2

Release Date:03.04.2017
  • Vagga now installs locales package on ubuntu where no locale-gen binary exists in original image
  • Disabled universe and multiverse repositories in new ubuntu xenial images where they are enabled by default (this effectively reverts behavior of package installation to how it was before 31.03.2017 and also consistent with the all pre-xenial releases.
  • Implemented hard-link-identical-files setting (experimental)
  • Implemented storage-subdir-from-env-var setting (experimental), for use in CI systems

  • Added experimental !CapsuleCommand and vagga _capsule command family
  • Added vagga _base_dir and vagga _relative_work_dir commands for easier script usage
  • Changed internal commands to vagga __cmd__ of arg zero, this allows symlinking vagga to different names
  • Added optional auto-indexing of all images (not useful for now)
  • Added lock on apt-get remove to remove race condition on parallel builds

Vagga 0.7.0

Release Date:19.01.2017
  • Added support of custom command-line options with help for all kinds of commands
  • Added !Persistent volumes (#204)
  • Added isolate-network option for commands and command-line option
  • Added isolate-network option for !RunAs build step
  • Py2/Py3Requirements now properly hashes files containing -r (basically includes)
  • Added include-regex option for !Copy
  • !Snapshot root now preserves ownership and permissions of source directory
  • !Depends now supports directories and include-regex, being on par with !Copy command for features
  • Added expect-inotify-limit option
  • Fixed PHP integration commands for Ubuntu xenial and Alpine v3.4
  • Multiple vagga _clean can now be run in single directory without issues (this is mostly useful in CI and scripts)
  • Added a warning when vagga.yml (not yaml) is present
  • Fixes bug with wrong precedence of directories in PATH when running a command using vagga _run
  • Allow mounting files (not only dirs) as external volumes
  • Added files option to !Tmpfs volume
  • Added umask option to !Copy
  • !Copy and !Depends no longer respect mode for generating hashes, only executable bit is used
  • Allow to copy from different container when using !Snapshot volume
  • Added data-dirs option for container
  • Added AlpineRepo and Repo commands
  • Supports !*Include directive to compose multiple files
  • Fixed environment variable precedence (#326)

  • Fixed external-user-id for !RunAs
  • vagga _list -A now includes hidden commands as expected
  • ca-certificates are now added to BuildDeps whenever any build tools are installed (by Py2Install, NpmInstall and similar commands)
  • /run volume mounted by default has now mode 0o755 (had 0o766 by a mistake)
  • Fixes bug with remounting to readonly on volumes that were previously mounted with nosuid, nodev or few other options
  • eatmydata is only enabled for !Install and !BuildDeps rather than everything because it conflicts with some other ``LD_PRELOAD``ed things (like faketime)
  • Added vagga _clean --volumes and vagga _clean --unused-volumes
  • Implemented vagga _clean --everything (again after 0.2)
  • Upgraded embedded alpine tools (apk-tools 2.6.8, busybox 1.25.1)
  • Vagga does not output environment of a running command any more, use VAGGA_DEBUG_CMDENV to show
  • Removed writing /tmp/vagga/hosts in !Supervise commands, it was rarely useful and never documented

Vagga 0.6.1

Release Date:14.06.2016
  • Blacklists some non-working alpine mirrors

Vagga 0.6.0

Release Date:11.06.2016
  • vagga uses rust 1.9 and ubuntu xenial for building
  • Refactored internals to use traits for commands instead of large enum. This makes adding more commands much easier.
  • Ubuntu images are now fetched from http://partner-images.ubuntu.com rather than http://cdimage.ubuntu.com
  • vagga now uses single level of uid mappings and doesn't use the actual mapping as part of container hash. This allows to use mount in container more easily and also means we have reproducible containers hashes across machines
  • !Copy: fixed crash on absent directories, fix copying paths outside of the /work
  • Uses libmount for many mount operations (not all yet)
  • Added keep-composer and vendor-dir options to !ComposerSettings
  • New command !Unzip similar to !Tar
  • Implement (optional) checksum checking in !Tar and !TarInstall
  • The minimum-vagga now works even when it doesn't know all the commands in the config (still YAML syntax must be correct)
  • Add support for volumes in commands (not only in containers)
  • Vagga now uses tar-rs library for unpacking archives instead of busybox, this may mean some features are new, and some archives could fail (please report if you find one)
  • Add !Container volume type, which allows to mount other container as a volume, mostly useful for deployment tools
  • Vagga now runs id -u -n for finding out username, previously was using long names which aren't supported by some distributions (alpine == busybox)
  • Root user may now run vagga without /etc/subuid this makes container in container scenario easier
  • Failed remount read-only is now a warning, this has two implications: you can run vagga on tmpfs and in this case your root image is writable
  • Add vagga -m which allows to run multiple vagga commands in sequence
  • Add prerequsites option, which allows to run sequences of commands in different containers
  • Add pass-tcp-port which allows to test systemd-like socket activation and other scenarios that need passing tcp socket as file descriptor
  • Add image-cache-url option which allows to fetch cached image from somewhere instead of building it locally
  • !Tar command now supports getting tar from /volumes/
  • Add !RunAs command which allows to get rid of sudo and su in build steps
  • Add --at-least option for vagga _clean --unused
  • !Build command can copy file (previoulsy could only directory)
  • Add build-lock-wait setting to allow simultaneous builds of containers
  • Package lists from apt-get are now cached for each distribution and doesn't fail on concurrent builds
  • Add --allow-multiple option to _init_storage_dir
  • Commands with name starting with underscore are not listed in vagga and vagga _list by default (like built-in ones)
  • Ubuntu commands now use libeatmydata by default, which makes installing packages about 3x faster
  • We remove /var/spool/rsyslog in ubuntu, this is only folder that makes issues when rsyncing image because of permissions (it's not useful in container anyway)
  • BuildDeps now don't try to apt-mark in subcontainer
  • Updated quire requires you need to write !*Unpack instead of !Unpack
  • Remove change-dir option from SubConfig that never worked and was never documented

Vagga 0.5.0

Release Date:03.04.2016
  • !Depends doesn't resolve symlinks but depends on the link itself
  • Pseudo-terminals in vagga containers now work
  • !Remove removes files when encountered (previously removed only when container already built), also the command works with files (not only dirs)
  • Add !Shapshot`, ``!Empty, !BindRO volume types
  • Add external-volumes setting, which allows to mount directories outside of the project dir
  • Add minimum-vagga option, which hints user which version they should use
  • Implement !Build, !Download, !Copy build steps
  • Add _init_storage_dir builtin command
  • Add vagga _clean --unused mode of operation which is superior to --old
  • Allow to customize python and nodejs versions for Py* and Npm* steps
  • Fix various bugs in networking implementation
  • Add shell autocomplete (bash included, zsh can be configured)
  • The .vagga/.mnt is now unmounted during build (fixes bugs with bad tools)
  • Improved SIGINT handling, now Ctrl+C in interactive processes such as python (without arguments) works as expected
  • The signal messages ("Received SIGINT...") are now printed into stderr rather than stdout (for !Supervise type of commands)
  • Killing vagga supervise with TERM mistakenly reported SIGINT on exit, fixed
  • Signal SIGQUIT is now correctly propagated
  • Add PHP/Composer support
  • Add Ruby/Bundler support
  • Add support for arch parameter in !UbuntuRelease this changes hash sum of all containers built using !UbuntuRelease
  • The stdin redirected from /dev/null and stdout is redirected to stderr during the build
  • You can now filter commands in supervise by tags
  • Change gateway network from 172.18.0.0/16 to 172.23.0.0/16, hopefully this will have less collisions
  • The TERM and *_proxy env vars are now propagated for supervise commands in the same way as with normal commands (previously was absent)
  • Implemented shared image cache via _push_image command and image-cache-url option

Vagga 0.4.1

Release Date:03.11.2015
  • !Tar and !TarInstall commands now support unpacking local files (#81)
  • Container build process now locked, which avoid failure with cryptic error message on simultaneous builds (#80)
  • Add _pack_image command
  • Upgrade rust to v1.4.0
  • Renamed and fixed vagga_network command as vagga _network subcommand
  • The pip cache is now namespaced over distro and version (was singleton)
  • Vagga now cleans apt lists cache on failed apt-get update (#108)
  • Add UbuntuPPA and AptTrust build steps

Vagga 0.4.0

Release Date:11.10.2015
  • Vagga now uses "unshare" and "signal" crates for working with containers
  • Signal handling is changed:
    • User visible changes: Ctrl+C doesn't sent twice to children (was rarely noticeable), Ctrl+/ reliably kills vagga and children
    • The only signal that is propagated by vagga to children is now SIGTERM
    • SIGINT is never propagate to children by vagga itself (because it's usually sent to process group anyway by Ctrl+C)
    • Other signals like SIGQUIT (SIGHUP, SIGUSR1, ...), are not captured by vagga, so they terminate vagga, resulting child processes are killed by OS by the KILL signal).
    • So if you want to send one of the signals except SIGTERM, send it to the specific process not to vagga
  • Fix broken !Alpine, which always installed latests known version of the distribution instead specified
  • Add kill-unresponsive-after setting
  • In ubuntu guests by default /usr/bin/chfn is symlinked to /bin/true, this prevents errors on some host systems (#52), this changes hash of the !UbuntuRelease step
  • Fix --only and --exclude for supervision commands (was broken since 0.2.0)
  • Add --no-build and --no-version-check options
  • Fixed epilog option
  • Implement support of git+https and hg+https urls in python requirements (#58)
  • Add support of Py3Requirements/Py3Install for alpine (v3.2 has python3)
  • Mount /dev/shm by default (needed for ubuntu host, fixes #32)
  • Implement forwarding proxy variables by default (#38)
  • Run !Sh scripts with -ex options (#72)
  • Implement subdirs key for !Tmpfs volume
  • Support tilde-expansion in storage-dir and cache-dir settings
  • The /etc/hosts file now copied inside the container at start (#39)

Vagga 0.3.0

Release Date:30.08.2015
  • !Tar command without subdir specified ignores invisible files and dirs (ones starting with dot .) to determine subdir.
  • Vagga now list of packages and log of duration of each step at a container folder (e.g. .vagga/container_name/../timings.log)
  • Add !UbuntuRelease builder to build non-lts ubuntu
  • Add !Git and !GitInstall commands to install from git repository (similar to !Tar and !TarInstall)
  • Add user-id and external-user-id settings
  • Implement !SubConfig build step (very experimental)
  • Add trusted-hosts to !PipConfig
  • Add timings.log and various package lists to the container metadata for easier troubleshooting
  • Add BindRW subvolume type
  • No longer clean /var/lib/apt by default (better for reusing containers)

Vagga 0.2.5

Release Date:03.03.2015
  • A quick bugfix release of NpmInstall command

Vagga 0.2.4

Release Date:03.03.2015
  • Implement support of https links for Tar, TarInstall commands
  • The !Py* commands now download latest pip via get-pip.py. This effectively means (a) that new features (like checkout a git subdirectory) works, (b) the version of pip is uniform across distributions and (c) installing dependencies to not interfere with pip dependencies on ubuntu (e.g. previously requests library where removed when removing build dependencies)
  • Fix !CacheDirs command which was broken few versions ago
  • Add !Text command for easier writing files into container (e.g. configs)

Vagga 0.2.3

Release Date:19.02.2015
  • Reasonable error message when not enough uids available (#7)
  • When running as root vagga now can use all available uids and doesn't require subuid/subgid files setup, mostly useful for container-in-container scenarios (#7)
  • The VAGGAENV_* environment vars will now be propagated to containers with the prefix stripped
  • vagga now supports --env and --use-env command-line switch to set envionment variable for child processes and to propagate a variable from parent (i.e. user's) environment
  • Add !Container build command, which may be used to build on top of another container
  • The vagga _run now works with relative commands
  • Experimantal auto-clean option for containers
  • Add node-legacy as dependency of !Npm for ubuntu (required for many scripts)

Vagga 0.2.2

Release Date:14.02.2015
  • Add _version_hash command, mostly for scripting
  • No need for tilde or null after !UbuntuUniverse (and probably other cases)
  • Fix permission of ubuntu policy-rc.d, which fixes installing packages having a daemon that start on install
  • Configure apt to always use --no-install-recommends in ubuntu
  • Add -W flag to _run command, to run writable (copy of) container
  • Ubuntu will automatically use nearest mirror and allow to customize mirror in personal settings

Vagga 0.2.1

Release Date:12.02.2015

This release fixes small issues appeared right after release and adds python requirements.txt support.

  • make install did not install vagga's busybox, effectively making vagga work only from source folder
  • Add Py2Requirements and Py3Requirements commands
  • Implement writing /etc/resolv.conf (previously worked only by the fact that libc tries 127.0.0.1 when the file is empty)
  • Fix positional arguments for shell-wrapped commands

Vagga 0.2.0

Release Date:11.02.2015

This is backwards-incompatible release of vagga. See Upgrading. The need for changes in configuration format is dictated by the following:

  • Better isolation of build process from host system
  • More flexible build steps (i.e. don't fall back to shell scripting for everything beyond "install this package")
  • Caching for all downloads and packages systems (not only for OS-level packages but also for packages installed by pip and npm)
  • Deep dependency tracking (in future version we will not only track changes of dependencies in vagga.yaml but also in requirements.txt and package.json or whatever convention exists; it's partially possible using Depends build step)

More features:

There are some features missing, but we believe it doesn't affect a lot of users.
