rdmsm4x-changelog-20260831-1856-central-fleet-container-management-setup
Configured centralized fleet container orchestration from rdmsm4x
across all 6 macOS fleet hosts for OrbStack and Podman, registering
remote Docker contexts, deploying standardized non-interactive SSH
environments, and building the fleet-containers unified CLI
tool.
Scope
- Lead Controller:
rdmsm4x - Managed Fleet Hosts:
rdmbair15m5,rdmbair13m5,jdmbair13m5,rdmpw3265m,rdmpw3275m - Engines & Tools: OrbStack, Podman Desktop,
Docker Engine,
docker context,fleet-containersCLI
Deliverables & Configurations
- Remote Docker Contexts Registered:

- Environment Normalization:
- Standardized
~/.zshenvacross all spoke hosts, ensuring automated PATH discovery for non-interactive SSH subshells.
- Standardized
- Central Management CLI:
- Created

fleet-containers status,fleet-containers ps [host|all],fleet-containers contexts,fleet-containers exec <host> <cmd>.
- Created
Verification Evidence
fleet-containers status: Probed all 6 nodes concurrently via ThreadPoolExecutor in <3s.fleet-containers ps: Successfully aggregated and rendered live telemetry for all 23 containers running acrossrdmsm4x,rdmpw3265m, andrdmpw3275m.fleet-containers exec rdmpw3265m docker ps: Executed remote container inspections seamlessly through SSH context tunnels.
