INTERNAL ERROR: cannot create temporary directory !: Docker environment

Yuta is learning Ruby and Rspec!

When I opened my portfolio site for the first time in a while, it turned out to be a screen I didn't want to see in a production environment. However, since this problem was raised in the docker issue on github, I was able to solve the problem relatively easily.

Also, because I was using RDS on AWS, the database was safe. RDS is expensive, but it's good mentally !!

environment

• Docker 19.03.5
• docker-compose 1.25.2
• nginx 1.15.8

Solutions

The solution is to delete the image of the container. However, the information inside the container may disappear ... The information was ambiguous there.

$ docker rm $(docker ps -a -q)
$ docker rm -f $(docker ps -a -q)
$ docker-compose build --no-cache

Cause

It seems that docker-compose will not start when the disk space of docker-compose is running low.

In other words, if you keep data or put together too much processing in the docker-compose file, the cache will accumulate, the docker-compose disk space will run out, and `ʻINTERNAL ERROR: cannot create temporary directory! `` will occur. ..
