-bash: docker-compose: command not found

If you Encounter this problem then it means that docker-compose is not installed. Let's install "docker-compose" now.

Prerequisites
Needless to say that you should have a running Docker installation. If you need to Install docker then follow this document Docker Installation & Configuration ON CENTOS 7.

We need to install the latest version of Docker Composer by downloading it from Github’s Docker Compose Repository Release Page, as the Official centos 7 repository does not have the the latest version. You can check the latest version on this page.

Download Docker Compose:

curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Example:

[root@appserver1 mycicdtest]# curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

[root@appserver1 mycicdtest]#

Set the permission to executable on "docker-compose"

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

Example:

[root@appserver1 mycicdtest]# chmod +x /usr/local/bin/docker-compose

Confirm the installation and verify the Docker Compose version number by typing following command:

docker-compose --version

Example:

[root@appserver1 mycicdtest]# docker-compose --version
docker-compose version 1.24.0, build 0aa59064
[root@appserver1 mycicdtest]#

Now you have successfully installed Docker Compose on CentOS 7. You can run "docker-compose" now.
