Atlassian

JIRA

Note: In this instance JIRA is configured (with `-v`) using a named volume, rather than a bind mount

 sudo docker volume create --name jira
 sudo docker run -d --name=jira -e TZ=Europe/London -e ATL_TOMCAT_SCHEME=https -e ATL_TOMCAT_SECURE=true -e ATL_PROXY_NAME=jira.bretts.org -e ATL_PROXY_PORT=443 \
   -p 7980:8080 \
   -v jira:/var/atlassian/application-data/jira \
   --restart unless-stopped \
   atlassian/jira-software

Docker JIRA runs with a uid and gid of 2001. To ensure they show up as a named user in the hosting system you can run:

 sudo addgroup --gid 2001 jira-docker
 sudo adduser --system --no-create-home --uid 2001 --gid 2001 jira-docker

Tips / Fixes

Tautulli slow to start

This may be due to an attempt to chown a large number of files. Login to the container:

 sudo docker exec -it <container> /bin/bash

Disable the chown step by editing /etc/cont-init.d/30-config and commenting out the chown command.

Adding an SSL cert for Unifi

 sudo openssl pkcs12 -export -inkey /etc/ssl/bretts.org/key.pem -in /etc/ssl/bretts.org/fullchain.pem -out /tmp/cert.p12 -name unifi -password pass:temppass
 sudo keytool -importkeystore -deststorepass aircontrolenterprise -destkeypass aircontrolenterprise -destkeystore /var/lib/unifi/data/keystore -srckeystore /tmp/cert.p12 -srcstoretype PKCS12 -srcstorepass temppass -alias unifi -noprompt
 sudo docker restart unifi-controller
 sudo rm /tmp/cert.p12

Local DNS resolution fails on docker 18.09

This may be the result of a bug: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1820278. Normally the container's /etc/resolv.conf should mirror that of the host, but in this case it seems to just be a default version. As a workaround, create /etc/docker/daemon.json with the following contents:

 {
   "dns": ["192.168.1.1", "8.8.8.8"],
   "dns-search": ["bretts.org"]
 }
