[MiniDLNA+podman] Health check always fails

Open ltguillaume opened this issue 2 years ago • 4 comments

I am using podman on Arch ARM. The health check for minidlna always fails on my system, causing a container exec_died journal entry and a restart every 10 sec.

podman[32243]: container exec a0ba94eb0da9e9e4dd7d92d0ead4b5286f0b0cd06f79bc10c26805113cccb5fc (image=docker.io/vladgh/minidlna:latest, name=minidlna, PODMAN_SYS)

Given the comment here (change localhost to 127.0.0.1), I have tried to use --health-cmd="curl --silent --fail 127.0.0.1:8200 || exit 1", but only --no-healthcheck solved the issue. I'm beginning to wonder if curl is even available in the image.

How are you running the container? I am not familiar with podman at all, yet, but from a brief google search, I see that the healthcheck syntax is different: --healthcheck-command 'CMD-SHELL curl --silent --fail localhost:8200 || exit 1'

Curl is present inside the image, the problem is probably in the check syntax and the difference between podman / docker

https://docs.podman.io/en/latest/markdown/podman-run.1.html says it's --health-cmd and "the command will be interpreted as an argument to /bin/sh -c"

I'm just running

podman run -d \
 --name minidlna \
 --net=host \
 -v /srv/containers/media:/media \
 -e MINIDLNA_MEDIA_DIR=/media \
 -e MINIDLNA_FRIENDLY_NAME=Pi \
 -e MINIDLNA_ROOT_CONTAINER=B \
 -e MINIDLNA_ALBUM_ART_NAMES=Folder.jpg/folder.jpg/Cover.jpg/cover.jpg \
 -e MINIDLNA_MERGE_MEDIA_DIRS=YES \
 -e MINIDLNA_WIDE_LINKS=YES \
 docker.io/vladgh/minidlna

Something else is going on, because I just tried the following and it works. Still, if I don't disable the health check, it will show exec_died every 10 seconds.

$ podman exec minidlna curl --fail --silent localhost:8200 || echo 1
<HTML><HEAD><TITLE>MiniDLNA 1.3.0</TITLE></HEAD><BODY><div style="text-align: center"><h2>MiniDLNA status</h2></div><h3>Media library</h3><table border=1 cellpadding=10><tr><td>Audio files</td><td>0</td></tr><tr><td>Video files</td><td>>

$ podman exec minidlna curl --fail --silent 127.0.0.1:8200 || echo 1
<HTML><HEAD><TITLE>MiniDLNA 1.3.0</TITLE></HEAD><BODY><div style="text-align: center"><h2>MiniDLNA status</h2></div><h3>Media library</h3><table border=1 cellpadding=10><tr><td>Audio files</td><td>0</td></tr><tr><td>Video files</td><td>>
