Cannot run any postgis-ram images

Feedback & Bug Reports

I have tried to run 9.6-postgis-ram 9.6.7-postgis-ram and 9.6.10-postis-ram. All of them fail with “no space left on device”:

How are you running this? Are you using it as a secondary container? Maybe you need to supply a command to specify start-up options.

#3

I ran it in circleci, then when testing attempted to run them in my local docker.

The parent containers (postgres , postgis) do not require any additional commands, and the postgres-ram container doesn’t require it either.

#4

If you can provide some replication instructions, someone may be able to take a look. The best approach is a small, open example on GitHub.

#5

docker run circleci/postgres:9.6-postgis - works.
docker run circleci/postgres:9.6-postgis-ram - does not work.

#6

Ah, i figured it out. Outside of the normal execution flow (locally or using setup_remote_docker) you have to add --tmpfs /dev/shm/pgdata/data for it to boot properly.
