# `node1-ssh` Skill
Use this skill to run read-only commands against **node1** (the Docker Swarm host) when:
Use this skill to run **read-only** commands against **node1** (the Docker Swarm host) when:
- A deploy failed and you need to inspect running services.
- You need to see a service's logs for debugging.
- An agent on homelab can't be reached and you want to check the stack from another node.
- You want to check the state of the stack on the swarm.
## How it works
Commands run via `ssh node1 <read-only cmd>`. The SSH alias is set up in `${HOME}/.ssh/config`
Commands run via `ssh node1 <cmd>`. The SSH alias is configured in `${HOME}/.ssh/config`
during this workflow (only when swarm secrets are configured for the caller repo).
Read access is enforced by the homelab repo's own OpenCode allowlist: **no other ssh hosts or any write commands on node1 are permitted**.
## Allowed commands
## What you're actually allowed to run — the allowlist is the source of truth
The following read-only commands work via `ssh node1`. Wrap your command in single quotes and escape any `$` signs used inside the remote shell.
This skill does **not** define which commands are permitted, and you must not assume a fixed
list here. The single source of truth for exactly which `ssh node1 …` commands are allowed is
the **caller repo's own OpenCode permission config** (e.g. `opencode.json` in the homelab repo:
a `deny "ssh *"` with specific `allow "ssh node1 …"` entries, last-match-wins).
- List services: `docker service ls`
- Service details: `docker service ps <name> [--format ...]`
- View logs: `docker service logs <name> [--tail N] [--since 24h] [--timestamps]`
- Network info: `docker network ls`, `docker network inspect <name>`
- Volumes: `docker volume ls [-f dangling=true]`
- Swarm nodes: `docker node ls`, `docker node inspect self`, `docker node ps --host node1`
The same read-only constraint applies — write commands on node1 are rejected by the allowlist even if they appear in other allowlists.
- Only read-only diagnostics are permitted; any write/mutating command on node1 is denied.
- The permission layer enforces this — if a command is not on the caller's allowlist it will be
blocked, regardless of what this skill or any other allowlist says.
- So: reach for `ssh node1 …` for read-only diagnostics, and treat the caller's `opencode.json`
`ssh node1` allow-entries as the authoritative list of what will actually run.
