CentOS 7 still ships a version of Docker with API version 1.24 which
does not support this argument. This commit uses `docker.rm` to remove
the container manually after the state is run, in cases where we were
using auto_remove=True.
Much Improved Support for Docker Networking
===========================================
The `docker_network.present` state has undergone a full rewrite, which
includes the following improvements:
Full API Support for Network Management
---------------------------------------
The improvements made to input handling in the
`docker_container.running` state for 2017.7.0 have now been expanded to
docker_network.present`. This brings with it full support for all
tunable configuration arguments.
Custom Subnets
--------------
Custom subnets can now be configured. Both IPv4 and mixed IPv4/IPv6
networks are supported.
Network Configuration in :py:func:`docker_container.running` States
-------------------------------------------------------------------
It is now possible to configure static IPv4/IPv6 addresses, as well as
links and labels.
Improved Handling of Images from Custom Registries
==================================================
Rather than attempting to parse the tag from the passed image name, Salt
will now resolve that tag down to an image ID and use that ID instead.
Due to this change, there are some backward-incompatible changes to
image management. See below for a full list of these changes.
Backward-incompatible Changes to Docker Image Management
--------------------------------------------------------
Passing image names to the following functions must now be done using separate
`repository` and `tag` arguments:
- `docker.build`
- `docker.commit`
- `docker.import`
- `docker.load`
- `docker.tag`
- `docker.sls_build`
Additionally, the `tag` argument must now be explicitly passed to the
`docker_image.present` state, unless the image is being pulled from a
docker registry.
This PR is part of what will be an ongoing effort to use explicit
unicode strings in Salt. Because Python 3 does not suport Python 2's raw
unicode string syntax (i.e. `ur'\d+'`), we must use
`salt.utils.locales.sdecode()` to ensure that the raw string is unicode.
However, because of how `salt/utils/__init__.py` has evolved into the
hulking monstrosity it is today, this means importing a large module in
places where it is not needed, which could negatively impact
performance. For this reason, this PR also breaks out some of the
functions from `salt/utils/__init__.py` into new/existing modules under
`salt/utils/`. The long term goal will be that the modules within this
directory do not depend on importing `salt.utils`.
A summary of the changes in this PR is as follows:
* Moves the following functions from `salt.utils` to new locations
(including a deprecation warning if invoked from `salt.utils`):
`to_bytes`, `to_str`, `to_unicode`, `str_to_num`, `is_quoted`,
`dequote`, `is_hex`, `is_bin_str`, `rand_string`,
`contains_whitespace`, `clean_kwargs`, `invalid_kwargs`, `which`,
`which_bin`, `path_join`, `shlex_split`, `rand_str`, `is_windows`,
`is_proxy`, `is_linux`, `is_darwin`, `is_sunos`, `is_smartos`,
`is_smartos_globalzone`, `is_smartos_zone`, `is_freebsd`, `is_netbsd`,
`is_openbsd`, `is_aix`
* Moves the functions already deprecated by @rallytime to the bottom of
`salt/utils/__init__.py` for better organization, so we can keep the
deprecated ones separate from the ones yet to be deprecated as we
continue to break up `salt.utils`
* Updates `salt/*.py` and all files under `salt/client/` to use explicit
unicode string literals.
* Gets rid of implicit imports of `salt.utils` (e.g. `from salt.utils
import foo` becomes `import salt.utils.foo as foo`).
* Renames the `test.rand_str` function to `test.random_hash` to more
accurately reflect what it does
* Modifies `salt.utils.stringutils.random()` (née `salt.utils.rand_string()`)
such that it returns a string matching the passed size. Previously
this function would get `size` bytes from `os.urandom()`,
base64-encode it, and return the result, which would in most cases not
be equal to the passed size.
This does the following:
- Splits states for container/volume/image/network management into four
separate state modules.
- Preserves backward compatibility by making ``docker.image_present``
invoke ``docker_image.present``, etc.
- Changes how Salt detects that a container needs to be replaced.
Instead of comparing each passed argument to the named container's
configuration, it creates a temporary container, and compares that
container to the named container. If the two differ, then the older
container is removed, and the new one is renamed and started, becoming
the named container.
- Removes the unit tests for container management and replaces them with
integration tests.
- Adds unit tests for the new salt.utils.docker
