## Common questions

### Do I need to run Tugtainer-Agent separately from the Tugtainer backend?

Yes. The backend and agent are separate pieces, so run them in separate terminal windows, such as python -m backend.dev and python -m agent.dev. If one isn't running, the app won't be able to manage containers.

### What security settings should I configure in the agent .env?

Copy .env.example to .env and set values like AGENT_SECRET. Keep ALLOW_EXEC=false unless you truly want the agent to run shell commands inside containers. If ALLOW_EXEC is enabled, a mistaken or bad request can run arbitrary commands in containers.

### Is there a known Tugtainer-Agent connection failure with HTTP 424?

Yes. A GitHub issue reports a failed connection to tugtainer-agent with HTTP 424 when using two agents after a first install. The issue notes that agents were a recent change at the time.

### Can Tugtainer use agents on multiple Docker hosts?

Yes. Tugtainer is described as supporting multi-host agents, rollback, and alerts.

### Does Tugtainer-Agent provide remote access to Docker hosts?

Yes. The agent part of Tugtainer provides secure remote access to Docker hosts.
