<div>/var/lib/docker/aufs takes a lot of space if many containers are running and </div>
<div>writing data to their volumes.</div>
<div><br>
</div>
<div>If the gate VM’s /var/lib/docker partition is small, you could move </div>
<div>/var/lib/docker to a different partition that is big enough (like /home or /tmp)</div>
<div>and create a symbolic link to /var/lib/docker.</div>
<div><br>
</div>
<div>mv /var/lib/docker /home/new_docker_path_with_more_space</div>
<div>ln -s /home/new_docker_path_with_more_space /var/lib/docker</div>
<div><br>
</div>
<div>Alternatively, you can use the -g option for the docker daemon to use a different</div>
<div>path instead of /var/lib/docker if it runs out of disk space.</div>
<div><br>
</div>
<div>DOCKER_OPTS="-g /home/new_docker_path_with_more_space"</div>
<div><br>
</div>
<div>Restart the docker daemon after making the above change.</div>

</div>
<div><br>
</div>
<div>
<div>
<div>Hi all,</div>
<div><br>
</div>
<div>I'm currently working to add new gates for the oraclelinux image base </div>
<div>type (<a href="https://blueprints.launchpad.net/kolla/+spec/oraclelinux-gate">https://blueprints.launchpad.net/kolla/+spec/oraclelinux-gate</a>) and
</div>
<div>had a question on size available in the gate VMs.</div>
<div><br>
</div>
<div>Right now the binary build is running out of space in the gate, as it </div>
<div>exceeds the 10GB we're allocating for /var/lib/docker. For me, a current </div>
<div>local build using binary+oraclelinux is clocking in at 10.01GB, where as </div>
<div>the centos+binary is a little smaller at 8.89GB.</div>
<div><br>
</div>
<div>Is it written anywhere exactly what space is available in the gate VMs? </div>
<div>Sam mentioned briefly that different providers used in the gate give a </div>
<div>variety of disk sizes, so do we have an idea what we can reasonably bump </div>
<div>the docker partition to?</div>
<div><br>
</div>
<div>The above number indicates centos will likely soon run into the same </div>
<div>problem as we dockerise more of the big tent, so I think it's a good </div>
<div>idea to check this now before more gates start falling over.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>-Paul</div>
<div><br>
</div>
<div>p.s. if people are interested here's lists sorted by name of the </div>
<div>oraclelinux and centos builds:</div>
