error starting container wtih "make run" - cannot start service app - trying to mount directory onto a file or vice versa #120

Closed meonkeys closed 5 years ago

meonkeys commented 5 years ago

make run doesn't work for me. I'm on Ubuntu 18.04 LTS and I installed Docker via snap.

The first error I got was:

$ make run

... 8< 8< 8< 8< (snip) 8< 8< 8< 8< ...

I noticed that ~/snap/docker/321/.taskrc was a directory, so I removed it, and ran touch ~/snap/docker/321/.taskrc.

Now make run exits successfully, but the container dies:

$ docker ps -a

Ruby then crashes trying to load a file:

This may be specific to snap-installed Docker and docker-compose. I cannot repro on another Ubuntu 18.04 LTS computer where Docker was installed via apt.

Try to remove .taskrc and initialize it with task command first. Docker version of taskwarrior-web relies on existing configuration. I suppose that the empty .taskrc file doesn't work.

Zebradil commented 5 years ago

I reproduced the issue. Doesn't matter which .taskrc is used.

Zebradil commented 5 years ago

FROM alpine was used in the Dockerfile. Switching back to alpine:3.7 solves the issue.
