With QEMU the ARM64 builds are slow and not reliable. If we use the
Docker Cloud builders we reduce the build times considerably.
As a Docker OSS organisation we get 400 build minutes per month, which
should be fine, because we already use checks if builds are really
needed. The Docker Cloud also uses a cache that should reduce build
times a little bit more.
With Debian the Quay.io security checker found several issues in the
image. With Ubuntu we have never versions of all packages and therefore
less (or no) issues.
We now serve Netbox with an nginx-unit instance instead of Gunicorn.
This allows us to get rid of the extra Nginx container because Unit is
also serving the static files. The static files are now collected at container
buildtime instead of every startup.
This checks if the source materials (python image, Netbox commit,
netbox-docker commit) have changed since the last build. This check is done
by comparing the digest and commit ids from the previous image with the
given tag to the current values taken from the Git and Docker repositories.
The checks are only performed for builds by the automated builds on Github.
When we don't set the --label argument on the commandline for all
build variants we lose them in the image.
This also prints out the labes on image push.
It also updates the README and the bug_report template to reflect
the changes. Additionally, in the README some relevant shields from
shields.io are added.
The labels follow [label-schema.org][lsorg] and the [OpenContainer
image spec, section annotations][ocis], specifications.
[lsorg]: http://label-schema.org/rc1/
[ocis]: https://github.com/opencontainers/image-spec/blob/master/annotations.md
This changes the build process even further. Instead
f using `wget` to fetch the current code, `git` is used.
This allows for faster switching between branches,
because only the differences between them have to be
fetched from the server.
But the main advantage is that the build cache can
finally be used as designed by Docker. Repetitive
builds are very fast now. This is also true between
branches and tags, as long as the `requirements.txt`
file doesn't change.
