--single-snapshot seems to be ignored

[cdprete]

Hello. I've a GitLab job like the following:

.docker:
  image:
    name: artifactory.foo.net/kaniko-project/executor:debug
    entrypoint: [ "" ]
  before_script:
    - APP_VERSION=$(cat "$APP_VERSION_FILE")
  script:
    - |
      if [ "$REPOSITORY_TYPE" = "" ]; then 
        /kaniko/executor --no-push --context "$CHART_PATH" --single-snapshot --use-new-run --build-arg APP_VERSION="$APP_VERSION"
      else
        /kaniko/executor --context "$CHART_PATH" --single-snapshot --cache=true --use-new-run --build-arg APP_VERSION="$APP_VERSION" --destination "news-docker-$REPOSITORY_TYPE-local.artifactory.foo.net/opensearchproject/opensearch:$APP_VERSION"
      fi
  rules:
  - exists: [ "$CHART_PATH/Dockerfile" ]

and from the output I can see that multiple snapshots are created, even if --single-snapshot is specified:

$ APP_VERSION=$(cat "$APP_VERSION_FILE") $ if [ "$REPOSITORY_TYPE" = "" ]; then # collapsed multi-line command INFO[0000] Retrieving image manifest artifactory.foo.net/opensearchproject/opensearch:2.14.0 INFO[0000] Retrieving image artifactory.foo.net/opensearchproject/opensearch:2.14.0 from registry artifactory.foo.net INFO[0000] Built cross stage deps: map[]

The Dockerfile is just

ARG APP_VERSION=2.14.0
FROM artifactory.foo.net/opensearchproject/opensearch:$APP_VERSION

RUN chmod -R 777 /usr/share/opensearch

Seeing the exact same thing, with the snapshotter taking a full filesystem snapshot at each new stage/FROM.

The kaniko arguments, related to caching etc, are like this:

--single-snapshot --snapshot-mode=redo --cache=true --cache-copy-layers=false --cache-ttl=24h --use-new-run

@cdprete have you noticed any difference without --use-new-run?

[cdprete]

Not at all.

@FilDevTronic does for you --snapshot-mode work? I see it being ignored as well for me: https://github.com/GoogleContainerTools/kaniko/issues/3233

[agilebean]

I can confirm that the flags --single-snapshot, --use-new-run, --snapshot-mode=redo

have no impact on the build snapshotting each layer.
