Instructions
Install docker
Installation of docker using a native docker script is one command, straight forward process. Before you run the below docker installation command ensure that curl package is installed on your system:
yum -y remove docker-common docker container-selinux docker-selinux docker-engine
yum -y install lvm2 device-mapper device-mapper-persistent-data device-mapper-event device-mapper-libs device-mapper-event-libs
# curl --version curl 7.29.0 (x86_64-redhat-linux-gnu)
Once ready, install docker using curl command which will download and execute a native docker installation script:
# curl -sSL https://get.docker.com/ | sh + sh -c 'sleep 3; yum -y -q install docker-engine' warning: /var/cache/yum/x86_64/7Server/docker-main-repo/packages/docker-engine-1.12.3-1.el7.centos.x86_64.rpm: Header V4 RSA/SHA512 Signature, key ID 2c52609d: NOKEY Importing GPG key 0x2C52609D: Userid : "Docker Release Tool (releasedocker) <docker@docker.com>" Fingerprint: 5811 8e89 f3a9 1289 7c07 0adb f762 2157 2c52 609d From : https://yum.dockerproject.org/gpg If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like: sudo usermod -aG docker your-user Remember that you will have to log out and back in for this to take effect! </docker@docker.com>
Enable and Start docker
To enable docker to start on your Redhat 7 Linux after reboot run the following command:
# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
To start docker daemon run:
# systemctl start docker
