Docker Container Once Stopped will not Run again!!!

[richard7ac]

Having broken my littlelink container trying to get it to upgrade I started again again from scratch with a new container, pull and new volume ... determined to make this work!!

Latest pull using v3.0.3 image sha256:6ce23bffd4cd5b17dcdfb09cdc7943ff4c75637da2c882f0671ac0cada82c111

I found the same issue that I saw before with the following messages appearing after a docker instance is stopped and restarted.

Updating Configuration: Apache Base (/etc/apache2/httpd.conf)
Updating Configuration: Apache SSL  (/etc/apache2/conf.d/ssl.conf)
Updating Configuration: PHP         (/etc/php8/php.ini)
Updating Configuration: Complete
Running Apache
AH00526: Syntax error on line 337 of /etc/apache2/httpd.conf:
Invalid command 'io', perhaps misspelled or defined by a module not included in the server configuration

Before restarting I extracted the HTTPD.CONF as I was expecting the problem and it looked like this at the offending location

    BrowserMatchNoCase ^healthcheck nolog
    CustomLog "logs/access.log" combinedio env=!nolog
</IfModule>

I then dumped the container as it was not running/runable and I had no persistent storage for /etc/apache2 setup to extract the httpd.conf file

    BrowserMatchNoCase ^healthcheck nolog
    BrowserMatchNoCase ^healthcheck nolog
    CustomLog "logs/access.log" combinedio env=!nolog
io env=!nolog
</IfModule>

I also ran a diff and these were the only differences!! (All empty lines stripped out from the above extracts)

Note that if I try to restart the httpd.conf is modified again and this time

    BrowserMatchNoCase ^healthcheck nolog
    BrowserMatchNoCase ^healthcheck nolog
    BrowserMatchNoCase ^healthcheck nolog
    CustomLog "logs/access.log" combinedio env=!nolog
io env=!nolog
io env=!nolog

</IfModule>

Hey @egooner I just confirmed this is indeed a bug.

More precisely, if you only mapped port 80 to something else, the docker will fail after stopping.
An easy way of fixing this should be just to map port 443 to something. You don't have to actually use it.

This did not happen in previous versions.
I was able to trace the bug to this commit 4f7443d.

I will revert this for now, and I will release a version that includes this shortly.

[JulianPrieber]

@STaRDoGG I had to revert your commit 4f7443d due to reasons stated above.

I'm not sure what's exactly causing this. Could you investigate?

[richard7ac]

OK - so are you referring to mapping port 80 and 443 for use outside of the container -

    --publish 80:80 \
    --publish 443:443 \

I do not map them at all as the Proxy is on the same logical network it communicates directly with it and by not exposing ports it means you cannot reach the backend without going through the proxy. Are you saying I should publish the ports as a work around?

[JulianPrieber]

Are you saying I should publish the ports as a work around?

Yes.

Alternatively, you can just wait for the temporary fix that should come out in about 15 minutes.

[richard7ac]

Correction - on the last one (I am using Portainer) I did have ports published

[JulianPrieber]

It took a bit, but this should do it for now: https://hub.docker.com/layers/julianprieber/littlelink-custom/latest/images/sha256-03c785dd9f0a53cc0fa4c48c6b34b38c03c49870815e319ddbb5b039a3e42133?context=explore

On my portainer instance, this is working fine now.

[richard7ac]

Great - many thanks - restart now works OK from a new container - I hope that this is OK I saved and copied over my database and it seems to have remembered the critical things.
I do still have an issue with the HTTPS mod but will raise that as a separate issue to avoid confusion

@STaRDoGG I had to revert your commit 4f7443d due to reasons stated above.

I'm not sure what's exactly causing this. Could you investigate?

Just at a super-quick lookover, I'm suspecting the search & replace is just getting screwed up somewhere near here, in docker-entrypoint.sh:

sed -i 's#CustomLog .* combined#BrowserMatchNoCase ^healthcheck nolog\n\n CustomLog "logs/access.log" combinedio env=!nolog\n#g' /etc/apache2/httpd.conf

Not sure what changed in the httpd.conf that would throw off the search regex though, that would have caused that; maybe the bump to the latest alpine or something. Probably just a matter of editing that S&R though. I can't really investigate for the next few days at least, though.

Looking at things right now, none of the php8 packages are available in Alpine 3.17:

(Looks like the maintainer is on it, but may take some time: https://gitlab.alpinelinux.org/alpine/aports/-/issues/13798)

vs 3.16:

https://pkgs.alpinelinux.org/packages?name=php8-*&branch=v3.16&repo=&arch=&maintainer=

So there's a decision to make there that I'll leave up to you before I mess with it any more. ;)

[JulianPrieber]

For now, my plan is to continue using Alpine 3.16

[jscottelblein]

Seems like I got it. You guys wanna give this container a test? No other changes needed:
