use-plain-http option not working

[MShekow]

What steps will reproduce the bug?

1. Create network: docker network create synctest
2. Run the registry: docker run -d --network synctest --network-alias registry registry:3
3. Attempt to run the sync: docker run --rm --user 0 -v $PWD/victoria-metrics-and-logs.yaml:/config.yaml --network synctest mirror.gcr.io/bitnami/charts-syncer:2.1.6 sync --config /config.yaml --from-date 2025-07-01 --use-plain-log --use-plain-http

With victoria-metrics-and-logs.yaml:

source:
  repo:
    kind: HELM
    url: https://victoriametrics.github.io/helm-charts
target:
  repo:
    kind: OCI
    url: http://registry:5000/victoriametrics
# Specifies the subset of charts to be synchronized
charts:
  - victoria-metrics-operator

skipArtifacts: true
skipImages: true

What is the expected behavior?

Sync should work

What do you see instead?

Clearly, the setting is not used, or I wouldn't see messages like "http: server gave HTTP response to HTTPS client"

Hi @MShekow, there is a new release of charts-syncer that should have fixed this issue.

See the version 2.1.7 - https://github.com/bitnami/charts-syncer/releases/tag/v2.1.7

[MShekow]

I can confirm that the fix works. Thanks!
