Compose: Mac /usr/local/bin/docker-compose: line 39: realpath: command not found

[HariSekhon]

The docker-compose shell wrapper from 'run as a container' installation does not work on Mac as it is looking for the realpath command:

https://docs.docker.com/compose/install/#install-compose

sudo curl -L --fail https://github.com/docker/compose/releases/download/1.19.0/run.sh -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

COMPOSE_FILE=docker/rancher-docker-compose.yml /usr/local/bin/docker-compose up

Docker for Mac's native binary version of docker-compose works normally.

AFAIK readlink -f does the same job as realpath and is more widely available.

[HariSekhon]

I used to use readlink a lot as a Linux systems engineer but the -f switch isn't available on Mac so it's not very portable:

readlink -f
readlink: illegal option -- f
usage: readlink [-n] [file ...]

[mefyl]

Ah, I guess that only stands for Linux then :/

You should be able to install the GNU version of realpath using brew install coreutils (you might have to declare a realpath=grealpath alias).
