One of the first application stacks I went to install and setup on my new Raspberry Pi docker cluster was Inspircd\/qwebirc\/anope. This stack was running originally on a raspberry pi 1b (256MB RAM version). I wanted to move this off the pi1 since it was out of date and would need a complete reinstall to be back to full patch status. However shortly after getting it running in my swarm, I ran into issues. <\/p>\n\n\n\n
The IRC server would restart every few hours, sometimes it would restart every 10 minutes or so. I deemed that as unacceptable on my basic setup even for just using it in development of IRC bots.<\/p>\n\n\n\n\n\n\n\n
The stability issues came from a over zealous health check for the server. I decided to build my own docker container for it that removed the health check. I started by grabbing the GIT repo for their docker container.<\/p>\n\n\n\n
git clone https:\/\/github.com\/inspircd\/inspircd-docker.git<\/code><\/pre>\n\n\n\nAfter cloning the repo, the only change I made was to comment out the healthcheck lines which can be seen below.<\/p>\n\n\n\n
HEALTHCHECK \\
--interval=15s \\
--timeout=3s \\
--start-period=60s \\
--retries=3 \\
CMD \\
\/usr\/bin\/nc -z localhost 6667<\/pre>\n\n\n\nAfter commenting out the healthcheck in the dockerfile, I rebuilt the container and pushed it to a local repository.<\/p>\n\n\n\n
docker build . -t inspircd\ndocker images # then find the latest build of the inspircd container and use the hex value from that\ndocker tag [hex] 127.0.0.1:5000\/inspircd\ndocker push 127.0.0.1:5000\/inspircd<\/code><\/pre>\n\n\n\nAfter updating my docker-compose file to reference the local repository copy of inspircd, I brought down the stack and redeployed it, this then used the newly built version of inspircd, fixing the health check problem, and providing much better uptime on the container.<\/p>\n","protected":false},"excerpt":{"rendered":"
