Each push will result in an image being tagged with latest
. If a release needs to be done, then git tag must be created:
git tag -a <major>.<minor> -m "relase"
(e.g.git tag -a 10.13 -m "relase"
)git push --tags
NOTE that in the example the tag is the same of the base image, so we can know what version of node has been build on.
