LPAR2RRD Docker Image

Good Day,

I am testing LPAR2RRD but via Docker. Can I assume that no data will be persistent ... and therefore I would like to ask if anyone has done anything that uses persistent storage.

We are primarily using it the VMWare component ...

Thanks

Shaun

    Hello,
    you can mount host directory into a container using -v parameter:
    docker run -d -p 80:80 -v /your/dir/on/host:/home xorux/apps
    Using this you'll have homedir (and all LPAR2RRD/STOR2RRD data) out of the container.

    Thanks ... I was going to go through normal installation docs to see what paths used.

    Nope ... that is not working ... even trying the following :

    docker run -d -p 8080:80 -v /data/lpar2rrd/lpar2rrd:/home/lpar2rrd/lpar2rrd/data -v /data/lpar2rrd/stor2rrd:/home/lpar2rrd/stor2rrd/data xorux/apps

    Can I assume that when the container starts, files are extracted and installed within :

    /home/lpar2rrd

    Example error doing your method :

    [da001903@poc000233 ~]$ docker run -d -p 8080:80 -v /data/lpar2rrd:/home xorux/apps

    docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"chdir to cwd (\\\"/home/stor2rrd\\\") set in config.json failed: no such file or directory\"\n".

    Creating the missing directory removes error but still leaves a non functioning website ...

    Ok ... bit of a cheat. I used the build doc for the docker image to rebuild what it did in /home and recreated it in /data/lpar2rrd and mounted that in /home ... worked ... but not ideal.
