Why is Docker installed but not Docker Compose?

Question

You also need to install Docker Compose. See the manual. Here are the commands you need to execute

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)"  -o /usr/local/bin/docker-compose
sudo mv /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

I'm installing on a Raspberry Pi 3, with Raspbian 8. The curl method failed for me (got a line 1: Not: command not found error upon asking for docker-compose --version) and the solution of @sunapi386 seemed a little out-dated, so I tried this which worked:

First clean things up from previous efforts:

sudo rm /usr/local/bin/docker-compose
sudo pip uninstall docker-compose

Then follow this guidance re docker-compose on Rpi:

sudo apt-get -y install python-pip
sudo pip install docker-compose

For me (on 1 Nov 2017) this results in the following response to docker-compose --version:

docker-compose version 1.16.1, build 6d1ac219

If you installed docker by adding their official repository to your repository list, like:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

Just do:

$ sudo apt-get install docker-compose

In case on RHEL based distro / Fedora:

$ sudo dnf install docker-compose

I'm on debian, I found something quite natural to do :

apt-get install docker-compose

and it did the job (not tested on centos)

I'm installing on a Raspberry Pi 3, on Raspbian OS. The curl method didn't resolve to a valid response. It also said {error: Not Found}, I took a look at the URL https://github.com/docker/compose/releases/download/1.11.2/docker-compose-Linux-armv7l and it was not valid. I guess there was no build there.

This guide https://github.com/hypriot/arm-compose worked for me.

sudo apt-get update
sudo apt-get install -y apt-transport-https
echo "deb https://packagecloud.io/Hypriot/Schatzkiste/debian/ jessie main" | sudo tee /etc/apt/sources.list.d/hypriot.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 37BBEE3F7AD95B3F
sudo apt-get update
sudo apt-get install docker-compose

first of all please check if docker-compose is installed,

$ docker-compose -v

If it is not installed, please refer to the installation guide https://docs.docker.com/compose/install/ If installed give executable permission to the binary.

$ chmod +x /usr/local/bin/docker-compose

check if this works.

just use brew:

brew install docker-compose
