[LINUX] Until docker-compose up on CentOS7

I checked it every time I did it several times, so I summarized it. I haven't done anything special.

https://docs.docker.com/install/linux/docker-ce/centos/

Delete old version

$ sudo yum -y update
$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

Docker Engine installation

Yum repository setup

$ sudo yum install -y yum-utils \
    device-mapper-persistent-data \
    lvm2

• yum-utils
• yum-config-manager is installed
• device-mapper-persistent-data/ lvm2
• Required for docker's devicemapper storage driver

$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

Add docker yum repository with

$ sudo yum install docker-ce docker-ce-cli containerd.io

Confirm when completed

$ docker --version
Docker version 19.03.5, build 633a0ea

Service start and auto start settings

$ sudo systemctl start docker
$ sudo systemctl enable docker

Docker Compose installation

https://github.com/docker/compose/releases

If not, install curl

$ sudo yum install -y curl

Installation

$ sudo curl -L https://github.com/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose

Verification

$ docker-compose --version
docker-compose version 1.25.4, build 8d51620a

Put yourself in the docker group. Now you can docker-compose without sudo. If you do this, log out and log in again.

$ sudo usermod -aG docker $USER

Create docker-compose.yml for confirmation.

$ vim docker-compose.yml
version: "3"
services:
  hello:
    image: hello-world:latest

docker-compose up!

$ docker-compose up

hello_1  |
hello_1  | Hello from Docker!
hello_1  | This message shows that your installation appears to be working correctly.
hello_1  |
hello_1  | To generate this message, Docker took the following steps:
hello_1  |  1. The Docker client contacted the Docker daemon.
hello_1  |  2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
hello_1  |     (amd64)
hello_1  |  3. The Docker daemon created a new container from that image which runs the
hello_1  |     executable that produces the output you are currently reading.
hello_1  |  4. The Docker daemon streamed that output to the Docker client, which sent it
hello_1  |     to your terminal.
hello_1  |
hello_1  | To try something more ambitious, you can run an Ubuntu container with:
hello_1  |  $ docker run -it ubuntu bash
hello_1  |
hello_1  | Share images, automate workflows, and more with a free Docker ID:

vagrant_hello_1 exited with code 0

that's all.
