Fix docker config paths

[markphelps]

a user has noted that some of our docs for running v2 in docker are incorrect. particularly around setting the flipt config file by mounting it to a file on the host.

as well as setting the storage path

example:

this is the correct way to configure a custom configuration file for flipt v2 with docker and persistent storage:

 docker run -d \
    -p 8080:8080 \
    -p 9000:9000 \
    -v $HOME/flipt:/var/opt/flipt \
    -v $HOME/flipt/config.yaml:/etc/flipt/config/default.yml \
    docker.flipt.io/flipt/flipt:v2

And config should list full path

storage:
  default: # id
    backend:
      type: local
      path: /var/opt/flipt

@claude can you fix the incorrect docker config paths for v2 docker instructions. look in all the v2 docs for places we mention docker

also if we don't already mention how to make the state persistent when running in docker we should add a section for it. if we do already have an example we should make sure it is correct

Fixed Docker Config Paths for v2 Documentation ✅

Successfully fixed the incorrect Docker configuration paths and enhanced persistent storage documentation.

Todo List:

• Search v2 docs for all Docker references
• Analyze current Docker documentation for incorrect paths
• Fix incorrect Docker config paths and mount points
• Ensure persistent storage documentation exists and is correct
• Test documentation changes
• Commit and push changes

Summary of Changes

Fixed Issues:

1. Corrected config mount path: Changed /etc/flipt/config.yaml to /etc/flipt/config/default.yml in installation.mdx
2. Enhanced persistent storage documentation: Added comprehensive example showing both data persistence and custom config
3. Updated login-with-github guide: Fixed Docker command to include proper mount paths and persistent storage
4. Added storage configuration example: Included proper YAML config showing path: /var/opt/flipt

Files Modified:

• docs/v2/installation.mdx - Main Docker installation documentation
• docs/v2/guides/operations/authentication/login-with-github.mdx - GitHub authentication guide

Key Improvements:

• All Docker examples now consistently use the correct mount path pattern
• Added detailed explanation of mount points and their purposes
• Included proper storage configuration in YAML examples
• Ensured persistent storage is properly documented across all v2 Docker guides

The documentation now accurately reflects the correct way to run Flipt v2 with Docker and persistent storage, matching the example provided in the issue.
