I am troubleshooting some errors on one of my cronjobs and I would like to make sure that the right image is being used by the pods. Is it possible to specify the image using the hash instead of the repo/name:tag syntax?
From the documentation:
The
imageproperty of a container supports the same syntax as thedockercommand does, including private registries and tags.
Which means it allows you to pull a hash based on the docker syntax for pulling a hash:
docker pull $DOCKER_REGISTRY/$NAMESPACE/$APP_NAME:$SHA1As Docker is (in most cases) the one responsible of image fetching, you can do as stated in their documentation - <repo>/<name>@sha256:<sha256>.
For example, if we'd like to use the image of Ubuntu with the SHA256 digest of 45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2, it would look something like ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
