Installing and Configuring Docker (Scientific Linux 7.3)

為什麼 Docker 官網所列出來有支援的作業系統沒有 Scientific Linux ? 但實際上是安裝的起來的，只是方法似乎比較不一樣，在 Adaptive Computing 這家公司的網站反而有提供方法，如下:

1. Make sure existing yum packages are up-to-date.

yum update

2. Install the Docker package.

yum install docker

3. Edit /etc/sysconfig/docker by replacing the existing OPTIONS line with the following.

OPTIONS='-s devicemapper --storage-opt dm.fs=xfs --exec-opt native.cgroupdriver=cgroupfs'

4. Start/restart Docker.

   systemctl restart docker.service

5. Set Docker to start after reboot.

   systemctl enable docker.service

6. Verify the installation.

   docker run dockerinaction/hello-world

【補充】
移除 docker:

yum remove docker

【Linux 指令】
安裝軟體前常常需要先確認一下自己的 Linux 的版本，這裡提供兩個常用的指令 ...

• lsb_release -a : 查看 Linux 的發行版本資訊

[steven@localhost ~]$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: Scientific
