OS: Linux 6.5 Ubuntu 22.04.4 LTS 22.04.4 LTS (Jammy Jellyfish)
CPU: (4) x64 unknown
Memory: 14.89 GB / 19.34 GB
Container: Yes
Shell: 5.1.16 - /bin/bash
Binaries:
Node: 22.6.0 - ~/.nvm/versions/node/v22.6.0/bin/node

Describe the bug

I'm using a self-hosted Trigger.dev stack deployed via Docker following the instructions [here](https://trigger.dev/docs/open-source-self-hosting) and [triggerdotdev/docker](https://github.com/triggerdotdev/docker).

The issue I noticed is that over 9000+ containers with names starting with task-run accumulate overnight, all with the exited status. I assume that Trigger.dev runs tasks in separate containers, but these containers are not being cleaned up automatically.

---

Steps to Reproduce:

1. Deploy Trigger.dev self-hosted using the official Docker setup.
2. Run tasks continuously for an extended period (e.g., overnight).
3. Observe the accumulation of containers named task-run* with an exited status.

---

Expected Behavior:

• Containers used for tasks should be cleaned up automatically after execution.
• Exited containers should not accumulate indefinitely.

---

Observed Behavior:

• Over 9000+ containers with the prefix task-run appear in the Docker environment overnight.
• These containers are all in the exited state, consuming resources and requiring manual cleanup.

• Deployment method: Self-hosted via Docker ([triggerdotdev/docker](https://github.com/triggerdotdev/docker))
• Container environment: LXC on Proxmox

Additional Information:

1. Is there an existing configuration to auto-remove containers after task execution (e.g., --rm flag)?
2. Could this be related to how Trigger.dev handles task container lifecycles?
3. Are there any recommendations or scripts for automatically cleaning up exited containers?

---

Temporary Workaround:
Manually running:

docker container prune

This removes all exited containers, but it's not a long-term solution.

---

Thank you for your support! Any guidance on resolving this container accumulation issue would be greatly appreciated.

Same for me. Any updates?

I wrote the code above, I just use crontab in which I created a task every 15 minutes that runs this code.

Having the same issue here, I need to clear them each day

why is this closed? Your crontab hack is not a solution!

The problem here is that the --rm flag is correctly mentioned in the log output but it is not actually in the command execution args!

"--rm",

missing from actual args
