This commit includes #310 patch for OCI images.
It also corrects the end of line format for kiwi/container/docker.py
and test/unit/container_image_docker_test.py, so flake tests are all
green.
This commit includes the --delete flag in order to synchronize the
docker images. This is relevant for derived images where the new
layer might not only add files, but also remove something from the
base image.
Fixes#309
This commit adds support for OCI images. Most of the docker related
code is reused for OCI classes and Docker classes have been refactored
so now they are a splecialization of the OCI classes. It is done this
way since KIWI internally only uses OCI format to operate with
containers, therefore docker images just differ from OCI images by
the way they are packaged or unpackaged.
Kiwi always uses OCI format for container manipulations, so it is
easier to assume the image kept between prepare and create step
is also in OCI format, this way less format convertions are needed.
First, commit refactors RootImport in order to also copy
the imported image after sychronizing the import.
Second, it includes a checksum of the copied image which is
validated in later steps.
This commit fixes the tagging schema for umoci. An OCI image
name is path[:tag], this commit rearranges some variable names to
avoid confusions between names and tags.
Fixes#249
Instead of creating a simple tarball the tools umoci and skopeo
from the docker tool chain are used to create official docker
images. Along with those tools more information to describe a
container has been added to the schema. A complete container
setup now consists of the following elements
<type image="docker">
<containerconfig name="..." maintainer="..." user="..." workingdir="...">
<entrypoint execute="command">
<argument name="option"/>
...
</entrypoint>
<subcommand execute="command">
<argument name="option"/>
...
</subcommand>
<expose>
<port number="..."/>
...
</expose>
<volumes>
<volume name="..."/>
...
</volumes>
<environment>
<env name="variable" value="value"/>
...
</environment>
<labels>
<label name="..." value="..."/>
...
</labels>
</containerconfig>
</type>
nose is no longer maintained, thus we have to move to another
testing system. This commit updates the tox setup and all tests
to use pytest instead of nose.
