According to the RancherOS console documentation, the following directories are persistent:

/home
/opt
/var/lib/docker
/var/lib/rancher

With that in mind, we can upload the binary to our /home directory and add it to our executable path.

--

To find the correct build, find the "machine hardware" architecture of your instance:

uname -m
# Example output: `x86_64`

Download the corresponding binary from the releases page and upload it to your server (using scp, rsync, etc..):

rsync --progress ./docker-compose-linux-x86_64 user@host:~/docker-compose-linux-x86_64

Login to your server and prepare the file:

# Create a `bin` directory to house our executables
mkdir ~/bin

# Move the file to the bin directory (renaming it in the process)
mv ~/docker-compose-linux-x86_64 ~/bin/docker-compose

# Make the file executable
chmod +x ~/bin/docker-compose

Assuming your shell is bash (to confirm, run echo $SHELL), create a .bash_profile document with the following contents to add our new directory to our executable PATH variable:

[ -d "${HOME}/bin" ] && export PATH="${PATH}:${HOME}/bin"

Only to add another possibility to AXE Labs and Vincents suggestion:

create a file /usr/bin/docker-compose with the following content:

#/bin/bash

docker run \
  -ti --rm \
  -v $(pwd):$(pwd) \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -w $(pwd) \
  docker/compose \
  $@

and another chmod +x /usr/bin/docker-compose

now you can use commands like docker-compose up as if it where installed!

RancherOS is a minimal installation of the Linux kernel, Docker daemon, and generally as little as possible else. docker-compose is not part of the default console.

Depending on what you're trying to do you can create a RancherOS service with docker-compose syntax: https://rancher.com/docs/os/v1.2/en/system-services/adding-system-services/

Or run actual docker-compose from a container: docker run docker/compose:1.10.0

Or switch to one of the persistent consoles and install it locally: https://rancher.com/docs/os/v1.2/en/configuration/switching-consoles/

Vincent's suggestion to use the compose container works, with some extra params:

$ cat > /tmp/docker-compose.yml << _EOF
> version: '3.0'
>
> services:
>
>   busybox:
>     image: busybox:latest
>     command: "/bin/sh -c 'sleep 30s'"
>
>   alpine:
>     image: alpine:latest
>     command: "/bin/sh -c 'sleep 60s'"
> _EOF
$ docker run -v /tmp:/tmp -v /var/run/docker.sock:/var/run/docker.sock -w /tmp docker/compose:1.14.0 up -d
Creating network "tmp_default" with the default driver
Creating tmp_busybox_1 ...
Creating tmp_alpine_1 ...
Creating tmp_busybox_1
Creating tmp_alpine_1 ... done
$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
7f0eccacd100        alpine:latest       "/bin/sh -c 'sleep..."   2 seconds ago       Up 2 seconds                            tmp_alpine_1
8f36a3cb1345        busybox:latest      "/bin/sh -c 'sleep..."   2 seconds ago       Up 2 seconds                            tmp_busybox_1

This was in RancherOS v1.0.1.
