Do not use this in production! #unstable
It's a project to test whether openITCOCKPIT works as a basically default installation in a docker container.
Even openITCOCKPIT in LXC is more stable than that.
The container should get an automatically bridged ip address from the default 172.17.0.0/24 docker bridge.
If you want to specify a custom ip, add --ip 172.17.0.3 \ as penultimate line to the setup command.
docker run -d --name oitc \
-v /sys/fs/cgroup:/sys/fs/cgroup:ro \
-v /var/run/docker.sock:/var/run/docker.sock \
--mount type=bind,source="$(pwd)"/installer.sh,target=/installer.sh \
--security-opt seccomp=unconfined \
--privileged \
fauust/docker-systemd:debian-10
docker exec -it oitc /installer.sh
Run nmap -sn 172.17.0.0/24 to get the assigned ip addresses.
Login at e.g. http://172.17.0.3 and register instance with the current community license key: e5aef99e-817b-0ff5-3f0e-140c1f342792
docker exec -it oitc /bin/bash
Use the frontend backup and restore functionality at https://172.17.0.3/#!/backups/index
Download a backup file from your old installation, copy it into the container and start a restore.
docker cp openitcockpit_dump_2020-08-18_12-05-00.sql oitc:/opt/openitc/nagios/backup/
After that logout and login with you user from the restored instance.
You may have to go to 'Manage User Roles', edit every role and click 'Update user role'.
To update openITCOCKPIT, log in to the container (docker exec -it oitc /bin/bash) and run apt-get update && apt-get upgrade.
After the update, manually check the files that are changed in the troubleshooting section below.
Stop and restart the container to make sure the update was successful and all services are working.
We don't save configs or backups in a host volume, due to missing migration scripts between configuration versions.
This feature may be added in the future. However, it is currently of no relevance to me.
In our default installation you don't need this. Please use a reverse proxy (nginx) instead!
This method can take a while with an installed openITCOCKPIT. There are some GBs to backup to the new image.
Use this example to bind 0.0.0.0:8081 to the docker internal port 443.
docker stop oitc
docker commit oitc oitc2
docker rm oitc
docker run -d --name oitc \
-v /sys/fs/cgroup:/sys/fs/cgroup:ro \
-v /var/run/docker.sock:/var/run/docker.sock \
-p 8081:443
--mount type=bind,source="$(pwd)"/installer.sh,target=/installer.sh \
--security-opt seccomp=unconfined \
--privileged \
oitc2
The currently used php fpm version of openITCOCKPIT is php7.3-fpm.
The socket path is defined at /etc/php/7.3/fpm/pool.d/oitc.conf and points to /run/php/php-fpm-oitc.sock.
Make sure the socket folder exists in the docker container: mkdir -p /run/php.
If php was not running, the required docker containers are also stopped.
Try to restart the container, after the php issue is fixed.
These commands were executed during the custom openITCOCKPIT installation.
Due to the openITCOCKPIT config generator, the customizations will be overwritten. So if there were still problems, execute these commands again.
