Docker tips and tricks
Using docker behind a proxy
<syntaxhighlight lang=bash>
- systemctl edit docker.service
</source> Enter the next three lines and save: <syntaxhighlight lang=ini> [Service] Environment="HTTP_PROXY=user:pass@proxy:port" Environment="HTTPS_PROXY=user:pass@proxy:port" </source>
Restart docker: <syntaxhighlight lang=bash>
- systemctl restart docker.service
</source>
Some useful aliases
I put this in my ~/.bash_aliases to maintain a check_mk container: <syntaxhighlight lang=bash> alias omd-log='docker container logs monitoring' alias omd-recreate-volume='docker volume create --driver local --opt type=nfs --opt o=addr=nfs.server.tld,rw --opt device=:/share monitoring' alias omd-root='docker container exec -it $(docker ps --filter name=monitoring -q) /bin/bash' alias omd-cmk='docker container exec -it -u omd monitoring bash' alias omd-start='docker container run --rm -dit -p 8080:5000 --tmpfs /omd/sites/omd/tmp:uid=1000,gid=1000 --ulimit nofile=1024 -v monitoring:/omd/sites --name monitoring -e CMK_SITE_ID=omd -e MAIL_RELAY_HOST='\smtp-gw.server.tld'\ -v /etc/localtime:/etc/localtime:ro checkmk/check-mk-raw:1.6.0p12' alias omd-stop='docker stop $(docker ps --filter name=monitoring -q)' </source>
