docker-compose.yml issues on Linux

[mdrovdahl]

Steps to reproduce

1. Follow "Running" steps in README.md
2. On step 2, use sudo docker up install, see below for why sudo...
3. Install fails b/c of path issues- WARNING: The PWD variable is not set. Defaulting to a blank string. and then ERROR: for simplenoteelectron_install_1 Cannot create container for service install: create .: volume name is too short, names should be at least two alphanumeric characters

What I expected

sudo docker-compose up install and sudo docker-compose up dev to work.

What happened instead

On Linux, it's not uncommon for docker to be setup such that docker commands require sudo. However, the $PWD in the volumes: sections of the docker-compose.yml don't get set properly with sudo.

markd@xps:~/dev/simplenote-electron$ docker-compose up install
ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
markd@xps:~/dev/simplenote-electron$ sudo docker-compose up install
WARNING: The PWD variable is not set. Defaulting to a blank string.
Creating simplenoteelectron_install_1 ... error

ERROR: for simplenoteelectron_install_1 Cannot create container for service install: create .: volume name is too short, names should be at least two alphanumeric characters

ERROR: for install Cannot create container for service install: create .: volume name is too short, names should be at least two alphanumeric characters
ERROR: Encountered errors while bringing up the project.
markd@xps:~/dev/simplenote-electron$ env | grep PWD
PWD=/home/markd/dev/simplenote-electron
OLDPWD=/home/markd/dev
markd@xps:~/dev/simplenote-electron$ sudo env | grep PWD
markd@xps:~/dev/simplenote-electron$

One workaround is to not run docker commands with sudo, ref: https://docs.docker.com/install/linux/linux-postinstall/ BUT it would be ideal if the docker-compose.yml worked with the sudo.

OS version

markd@xps:~/dev/simplenote-electron$ cat /proc/version
Linux version 4.9.0-6-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07)

Another workaround is to set the $PWD variable to the absolute path of your "simplenote-electron" directory with on the command line...eg:

sudo PWD="/home/markd/dev/simplenote-electron" docker-compose up install

Closing as this issue doesn't necessarily need action, more an FYI for others.

Since you left this off as an FYI, hopefully this helps too cause I came across this thread after running into something similar (completely unrelated to this project).

sudo has an -E flag that passes the environment (current user for most people probably) to the shell created by sudo.

So instead of sudo PWD="/home/markd/dev/simplenote-electron" docker-compose up install, you could do:

sudo -E docker-compose up install
