Install ClusterControl for FREE How to Deploy Your PostgreSQL Containers with ClusterControl Open a web browser and go to DockerвЂ™s physical host IP address with the mapped port, e.g, click on вЂњImport Existing Server/ClusterвЂќ, and then add the following information. Now, we can start to import the cluster into ClusterControl. Then, attach to the ClusterControl container interactive console: $ docker exec -it clustercontrol bashД¬opy the SSH key to all database containers: $ ssh-copy-id 172.17.0.6 To know it, we can run the following command for each node: $ docker inspect |grep IPAddress

For this, we need to know the IP Address for each database node. The last step is setting up the passwordless SSH to all database containers.

You should now see the ClusterControl main page. Open a web browser, go to and create a default admin user and password. Verify the ClusterControl container is up: $ docker ps | grep clustercontrolД§eadb6bb72fb severalnines/clustercontrol '/entrypoint.sh' 4 hours ago Up 4 hours (healthy) 22/tcp, 443/tcp, 3306/tcp, 9500-9501/tcp, 9510-9511/tcp, 9999/tcp, 0.0.0.0:5000->80/tcp clustercontrol Start the ClusterControl container (if itвЂ™s not started) and forward port 80 on the container to port 5000 on the host: $ docker run -d -name clustercontrol -p 5000:80 severalnines/clustercontrol $ docker exec -it sed -i 's|^#PermitRootLogin.*|PermitRootLogin yes|g' /etc/ssh/sshd_config $ docker exec -it sed -i 's|^PermitRootLogin.*|PermitRootLogin yes|g' /etc/ssh/sshd_config $ docker exec -ti apt-get install -y openssh-server openssh-client

Once done, use the вЂњImport Existing Server/ClusterвЂќ feature and the cluster should be imported into ClusterControl.ДЇirst, letвЂ™s Install OpenSSH related packages on the database containers, allow the root login, start it up and set the root password: $ docker exec -ti apt-get update Then allow passwordless SSH from ClusterControl to the database containers. The only requirement is to ensure the target containers have SSH related packages installed (openssh-server, openssh-clients). If you already have a PostgreSQL cluster running on Docker and you want ClusterControl to manage it, you can simply run the ClusterControl container in the same Docker network as the database containers. Now that you've setup your PostgreSQL cluster, you still need to monitor it, alert in case of performance issues, manage backups, detect failures and automatically failover to a healthy server. How to Import Your PostgreSQL Containers into ClusterControl Then, you can create a database user, change the configuration according to your requirements or configure replication between the nodes manually. Now, you can access each node with the following command: $ docker exec -ti bash $ docker run -d -name node3 -p 6553:5432 postgresДЄfter running these commands, you should have this Docker environment created: $ docker psД¬ONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESДҐ1038dbe21f8 postgres 'docker-entrypoint.sвЂ¦' About an hour ago Up About an hour 0.0.0.0:6553->5432/tcp node3Д«7a4211744e3 postgres 'docker-entrypoint.sвЂ¦' About an hour ago Up About an hour 0.0.0.0:6552->5432/tcp node2Дў29c6bd23ff4 postgres 'docker-entrypoint.sвЂ¦' About an hour ago Up About an hour 0.0.0.0:6551->5432/tcp node1 $ docker run -d -name node2 -p 6552:5432 postgres So, we need to pull the image: $ docker pull postgresДЄnd run the node containers mapping a local port to the database port into the container: $ docker run -d -name node1 -p 6551:5432 postgres Postgres The PostgreSQL object-relational database syвЂ¦ 6519 NAME DESCRIPTION STARS OFFICIAL AUTOMATED The image is available on Docker Hub and you can find it from the command line: $ docker search postgres How to Deploy PostgreSQL with DockerДЇirst, letвЂ™s see how to deploy PostgreSQL with Docker manually by using a PostgreSQL Docker Image.

In this blog, weвЂ™ll see how we can easily deploy a PostgreSQL setup via Docker, and how to turn our setup in a primary/standby replication setup by using ClusterControl.

This gives a significant performance boost and reduces the size of the application. Docker could be considered as a virtual machine, but instead of creating a whole virtual operating system, Docker allows applications to use the same Linux kernel as the system that they're running on and only requires applications to be shipped with things not already running on the host computer. It allows us to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. Docker has become the most common tool to create, deploy, and run applications by using containers.
