| == Creating a docker postgres image ==
| |
| This exposes the default port 5432 for postgres
| |
| docker run --name postgresq-spring -e POSTGRES_USER=iain -e POSTGRES_PASSWORD=password -p 5432:5432 -v /data:/var/lib/postgresql/data -d postgres:alpine
| |
|
| |
| The -d is to run the container in the background<br>
| |
| The postgres:alpine is the image name<br>
| |
| The -p is the port to expose which is the default for postgress
| |
| The -v is where the data will be stored

| ==Running a Container==
| |
| Sample for running a container with name test, ip 172,18.0.11, network to run on as billnet, capital P to expose the port (not for production), remove container when exit, it to have the errors go to the host console, and ps/dataservice for the image name
