The previous changes help with deleting some of the unused tags (roughly half of
the previous 30~40), but do not help in some cases and it's therefore impossible
to remove the remaining ones.
Currently, this is what happens:
a) repoapi retrieves this url for a project, e.g. for a tag in data-hal-jessie:
https://repoapi.mgm.sipwise.com/docker/tag/3534/ and uses tag.reference
gets the "reference" attribute:
sha256:fa18c06b84b17b19bed1d14b0b9d836bffba1531e68721dc8ad0a65cc7477761
b) manage_docker.sh (which works correctly) uses this complex command:
curl -vsiL -H "${curl_docker_header}" -X GET "${docker_url}/${docker_tag}" | sed -ne 's/^Docker-Content-Digest: \(sha256:[[[:alnum:]]\+\).*$/\1/ip;Tn;q;:n'
and with this input:
curl -vsiL -H 'Accept: application/vnd.docker.distribution.manifest.v2+json' -X GET \
'https://docker.mgm.sipwise.com:5000/v2/data-hal-jessie/manifests/I30522e47cadb23b042e48f23b5a509dc9abf6ccb'
gets as reference:
sha256:ebc37e95c8844d37ec174d6208f80d664a5d099802d839cde0a4f74424d317fe
c) from stackoverflow in
https://stackoverflow.com/questions/38795240/delete-image-from-docker-registry-v2
it is suggested to take json.config.digest of the output of the url above (instead
of headers, like manage_docker.sh), and that is:
"config": {
"mediaType": "application/vnd.docker.container.image.v1+json",
"size": 4915,
"digest": "sha256:fac5e71f2f690379d5fad98c550cb451a8c5197f529e519adaab7a66cef00019"
},
which is again different from both values above.
So this change adds code to remove in a way that mimics case b), in addition to
the existing one, in another attempt to completely fix the issue.
(It is not very elegant and it would be nice to pinpoint the exact problem
without these trial and error cycles by pushing to production, but it's
difficult when it depends on a running environment and the tools are not well
known to us, e.g. Django.)
Change-Id: I46859e369f039fffa3e191afb92c60df77d7e6e5
* we need to use reference ( docker API it doesn't support tag name )
* fix tag date (value in the first occurrence not last)
Change-Id: I2fa2f7bedaca4cdeeb3a3a2d4a3f4a661d15fad1
* provide info of actual images and tags
* refresh docker images/tag via release_dashboard
* keep that info in db
* fix Dockerfile documentation
* cleanup thanks to flake8
