Possible causes:

|
- Docker Daemon not started
|

|
|
- Linux: confirm via your init system
|
||
|
|
- macOS w/ docker-machine: run `docker-machine ls` and `docker-machine start <name>`
|
||
|
|
- macOS w/ Docker for Mac: Check the menu bar and start the Docker application
|
||
|
|
- DOCKER_HOST hasn't been set or is set incorrectly
|
||
|
|
- Linux: domain socket is used, DOCKER_* should be unset. In Bash run `unset ${!DOCKER_*}`
|
||
|
|
- macOS w/ docker-machine: run `eval "$(docker-machine env <name>)"`
|
||
|
|
- macOS w/ Docker for Mac: domain socket is used, DOCKER_* should be unset. In Bash run `unset ${!DOCKER_*}`
|
||
|
|
- Other things to check:
|
||
|
|
- Linux: User isn't in 'docker' group. Add and relogin.
|
||
|
|
- Something like 'sudo usermod -a -G docker ${USER}'
