BUG: netcat unavailable for HEALTHCHECK #156

Closed lilotter45 closed 1 year ago

lilotter45 commented 1 year ago

Description

netcat does not appear to be available in the snikket-portal container for the docker health check, despite being included in the dockerfile. Manually installing netcat in the container allows the command to run and the health state returns to "healthy."

My snikket-portal container was reporting an "unhealthy" state. While troubleshooting the issue, manually running the health check command (docker exec -it snikket-portal nc -zv 127.0.0.1 5280) returned the error OCI runtime exec failed: exec failed: unable to start container process: exec: "nc": executable file not found in $PATH: unknown.

Opening a shell in the container (docker exec -it snikket-portal sh) and running the same command (nc -zv 127.0.0.1 5280) resulted in the message sh: 1: nc: not found.

Running apt-get update && apt-get install netcat followed by the health check command, nc -zv 127.0.0.1 5280 results in the (presumably) expected result Connection to 127.0.0.1 5280 port [tcp/*] succeeded!.

To reproduce

Follow the instructions in the quick-start guide:

  1. Download the docker-compose.yml from https://snikket.org/service/resources/docker-compose.beta.yml
  2. Create snikket.conf in the same directory and update the domain name and admin email.
  3. For completeness (but probably not relevant to the issue): I also set SNIKKET_RETENTION_DAYS=28, SNIKKET_UPLOAD_STORAGE_GB=20, and SNIKKET_SITE_NAME=MySiteName
  4. Run the compose file docker compose up -d
  5. Check the status of containers docker container list

The following is returned:

Manually install netcat:

Thanks for the thorough report. This was already reported in #126 and fixed in #127 but the snikket/snikket-web-portal:beta image with id 997b1633a7ad is older than that. You could try with the snikket/snikket-web-portal:dev image with id 882d055ca3e0, it has netcat in it.

Thanks for the info. Sorry about the duplicate issue, I guess I didn't include closed issues in my search.
