Install Grafana on offline station with plugins

  • What Grafana version and what operating system are you using?
    Grafana 10.3.6, Ubuntu 20.04.6 LTS

  • What are you trying to achieve?
    Install Grafana and its plugins on an offline station.

  • How are you trying to achieve it?
    Build a custom Grafana image, using in Dockerfile command for plugin installation, like it define
    here

  • What happened?
    After the Helm installation, the plugin does not get installed, and the plugin files disappear from the container (custom Grafana image contains them)

  • What did you expect to happen?
    Plugin is installed with Grafana

  • Can you copy/paste the configuration(s) that you are having problems with?
    Dockerfile:

FROM grafana/grafana:10.3.6

# Remove / disable these to require authentication
ENV GF_AUTH_DISABLE_LOGIN_FORM "true"
ENV GF_AUTH_ANONYMOUS_ENABLED "true"
ENV GF_AUTH_ANONYMOUS_ORG_ROLE "Admin"

# Install a specific plugin
RUN grafana cli plugins install marcusolsson-json-datasource 1.3.12

USER grafana

ENTRYPOINT /bin/bash

I added following definitions to helm chart to avoid online signing and checks:

env: 
  GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS: "marcusolsson-json-datasource"
  GF_PLUGINS_VERIFY_SIGNATURES: "false"

grafana.ini:
  paths:
    plugins: /var/lib/grafana/plugins
  analytics:
    check_for_updates: false
    check_for_plugin_updates: false
  plugins:
    public_key_retrieval_disabled: true

Grafana logs after installation, no errors exist in log file, it is running but no plugins were installed:

when I add to helm chart:

plugins: 
  - marcusolsson-json-datasource 1.3.14

Grafana is topped by error with log:
