LPAR2RRD Docker Image

ShaunG

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.
