Docker Practice

1. Setup the repo: Link: https://docs.docker.com/engine/installation/linux/centos/#install-docker

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

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

2. Install Docker: sudo yum makecache fast sudo vi /etc/docker/daemon.json (empty file) Add these lines: { "storage-driver": "devicemapper" }

3. Start docker sudo systemctl enable docker sudo systemctl start docker sudo docker run hello-world

4. Download the Docker Machine binary and extract it to your PATH curl -L https://github.com/docker/machine/releases/download/v0.11.0/docker-machine-`uname -s-uname -m` >/tmp/docker-machine && chmod +x /tmp/docker-machine && sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

5. check version of docker-machine docker-machine version

6. enable the docker-machine shell prompt: vi ~/.bashrc Add these lines: PS1='[\u@\h \W$(__docker_machine_ps1)]$ '

7. Install bash completion for docker-machine (optional)

Install bash-completion script: cd Docker/bash-completion ./setup_bash_completion.sh

8. Install virtualbox driver on Centos 7 cd /etc/yum.repos.d/ sudo wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo yum update reboot (for new kernel to update) rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms yum search VirtualBox- ==> yum install - /usr/lib/virtualbox/vboxdrv.sh setup usermod -a -G vboxusers <your_user_name> (baohuynh, add user to group vboxusers)

9. Create docker-machine

• docker-manager create --driver Virtualbox manager1 (if not OK, use workaroud to download the latest boot2docker iso: curl -L https://github.com/boot2docker/boot2docker/releases/download/v17.05.0-ce/boot2docker.iso > ~/.docker/machine/cache/boot2docker.iso )
• docker-machine rm manager1 (rm old machine)
• docker-manager create --driver Virtualbox manager1 (create new one)

10. Install docker-compose

• curl -L https://github.com/docker/compose/releases/download/1.13.0/docker-compose-`uname -s-uname -m` > /usr/local/sbin/docker-compose
• chmod +x /usr/local/sbin/docker-compose
