In this scenario you will learn how to use the _--format__ parameters to pretty-print output from docker ps and docker inspect.
Steps
Formatting PS Output
Step 1 of 2
Example 1 - Names and Images as Table
The format of docker ps can be formatted to only display the information relevant to you.
Start Example Container
Start by launching a example container - docker run -d redis
Format
The standard docker ps command outputs the name, image used, command, uptime and port information.
To limit which columns are displayed, use the _--format__ parameter. The parameter allows pretty-printing containers using a Go template syntax.
docker ps --format '{{.Names}} container is using {{.Image}} image'
As it's using Go templates, it includes helper functions such as table.
docker ps --format 'table {{.Names}}\t{{.Image}}'
