still getting:

remote: Error response from daemon: Error processing tar file(exit status 1): write /app/node_modules/puppeteer/.local-chromium/linux-575458/chrome-linux/chrome: no space left on device

https://stackoverflow.com/questions/24671621/no-space-left-on-device

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

Digital Ocean dashboard indicates that we are out of SSD and RAM space ... 🙄 image

so I logged into the machine and ran:

reboot -h now

Based on: https://serverfault.com/questions/620595/best-way-to-gracefully-restart-centos image Of the system RAM 1882872 (1.8Gb) total, 1299252 (1.29Gb) is used and only 268800 (268Mb) available.

That did not have the desired effect because there are still way too many running Docker Containers (52!)

So I decided to "Nuke" the droplet with a power cycle! (which is obviously not recommended!) image

Obviously now there is no docker process running:

[root@centos-dokku-paas ~]# docker ps -a -q
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

After the power cycle:

[root@centos-dokku-paas ~]# sudo systemctl start docker
[root@centos-dokku-paas ~]# docker -D info

I read: https://medium.com/the-code-review/clean-out-your-docker-images-containers-and-volumes-with-single-commands-b8e38253c271 and ran the command:

docker system prune --all --force --volumes

Which had the following output:

Total reclaimed space: 3.356GB

Which is a start ... the RAM and Disk are no longer at 100% ... image

But it's still not a "solution"!

Re-started the build for the app that we are testing ... image

nelsonic commented 6 years ago

Now we have 420Mb of available RAM: image

But we still have way too many running docker containers: image

Fresh Start!

A complete Docker system clean can now be achieved by linking this with the full prune command covered earlier in this post.

docker container stop $(docker container ls -a -q) && docker system prune -a -f --volumes

Now when we run docker ps there are zero running docker containers.

let's rebuild all the dokku containers: dokku ps:rebuildall

nelsonic commented 6 years ago

Now the CPU, RAM and Disk are back to "normal" levels: image
