How to Deploy PostgreSQL on Docker Container. Who doesn’t want to learn a whole different technology before they can get down to playing with a brand-new database feature?

Type (or copy and paste) this into the Terminal window, being careful to use two minus signs before “name”, then hit return. Deploying PostgreSQL in a container is cost-efficient in terms of infrastructure, it also supports CI/CD development, and streamlines deployment and application management. So the other day, I thought about using Docker containers. For most of the other Docker objects, if you don’t specify a name, you end up having to use the hash key that Docker generates. It ensures standardization, such as in the transport sector, by choosing a single form of transport. Build agents that monitor and act on your behalf.

When a developer checks out the git repo with the application source code in it we want them to be able to run docker-compose up and have that work, this is why we expose port 15432 since the workstation might already have postgres installed and listening on the default port 5432.Our hope is that port 15432 is available on the developer's workstation.

Both the Terminal and Kitematic check to see if there is a default VirtualBox machine available, and if there isn’t, they create one. Note that this means your container is connecting through the VirtualBox machine, rather than directly. Omitting port after host part denotes that we will be using default postgres port defined in its own Dockerfile. Under db for the database we want the Docker image for Postgres 10.1 and use volumes to tell Compose where the container should be located in our Docker container. Estimated reading time: 5 minutes.
