Problem

Hi,

The docker_logs source incorrectly ignores the explicitly configured docker_host parameter when the value specifies a Unix socket (i.e., starts with unix:// or is a plain path). Instead of using the configured value, the source silently falls back to the connection logic that checks the DOCKER_HOST environment variable.

The issue is probably related to this change : #21088 as it's working in v0.48.0 but not in > v0.49.0

Regards,

Configuration

sources:
  my_docker_logs:
    type: "docker"
    # Explicitly set to Unix socket
    docker_host: "unix:///var/run/docker.sock"
