1. Redhat Rhel 7 Docker Image
2. Create Rhel 7 Docker Image

You can change Docker’s storage base directory (where container and images go) using the -g option when starting the Docker daemon.

This page shows how to install, setup and use Docker or Docker CE on RHEL 7 or CentOS 7 server and create your first container. How to install and use Docker on RHEL 7 or CentOS 7 (method 1) The procedure to install Docker is as follows: Open the terminal application or login to the remote box using ssh command: ssh user@remote-server-name. Remove Docker Container How to Run Nginx inside Docker Container. In this part we will concentrate on how you can run and access a network service, such as an Nginx web server, inside Docker, using the ubuntu-nginx image created earlier where the Nginx daemon was installed. Linux-based containers: This Docker image uses SQL Server 2017 Developer Edition on Linux on top of an Ubuntu 16.04 base image. This is meant to be run on Docker Engine on its multiple platforms. There are also Dockerfiles here for building RHEL & CentOS based images. Windows-based containers: These Docker images use SQL Server 2017 Express. I tried this method, but the instructions for Centos are only accurate for version 6.5 and below. Unfortunately I am running 7.0. I tried to revert everything by moving the /var/lib/docker directory back to its original location, but now when I run docker images or docker ps -a, I have no containers or images.

• Ubuntu/Debian: edit your /etc/default/docker file with the -g option: DOCKER_OPTS='-dns 8.8.8.8 -dns 8.8.4.4 -g /mnt'

• Fedora/Centos: edit /etc/sysconfig/docker, and add the -g option in the other_args variable: ex. other_args='-g /var/lib/testdir'. If there’s more than one option, make sure you enclose them in ' '. After a restart, (service docker restart) Docker should use the new directory.

Using a symlink is another method to change image storage.

Redhat Rhel 7 Docker Image

Caution - These steps depend on your current /var/lib/docker being an actual directory (not a symlink to another location).

Create Rhel 7 Docker Image

1. Stop docker: service docker stop. Verify no docker process is running ps faux
2. Double check docker really isn’t running. Take a look at the current docker directory: ls /var/lib/docker/
   2b) Make a backup - tar -zcC /var/lib docker > /mnt/pd0/var_lib_docker-backup-$(date +%s).tar.gz
3. Move the /var/lib/docker directory to your new partition: mv /var/lib/docker /mnt/pd0/docker
4. Make a symlink: ln -s /mnt/pd0/docker /var/lib/docker
5. Take a peek at the directory structure to make sure it looks like it did before the mv: ls /var/lib/docker/ (note the trailing slash to resolve the symlink)
6. Start docker back up service docker start
7. restart your containers
