Docker uses Go templates to allow users manipulate the output format of certain commands and log drivers. Each command a driver provides a detailed list of elements they support in their templates:
- Docker Images formatting
- Docker Inspect formatting
- Docker Log Tag formatting
- Docker Network Inspect formatting
- Docker PS formatting
- Docker Stats formatting
- Docker Volume Inspect formatting
- Docker Version formatting
Template functions
Docker provides a set of basic functions to manipulate template elements. This is the complete list of the available functions with examples:
Join
Join concatenates a list of strings to create a single string. It puts a separator between each element in the list.
$ docker ps --format '{{join .Names " or "}}'
Json
Json encodes an element as a json string.
$ docker inspect --format '{{json .Mounts}}' container
Lower
Lower turns a string into its lower case representation.
$ docker inspect --format "{{lower .Name}}" container
Split
Split slices a string into a list of strings separated by a separator.
{% raw %}
# docker inspect --format '{{split (join .Names "/") "/"}}' container
{% endraw %}
Title
Title capitalizes a string.
$ docker inspect --format "{{title .Name}}" container
Upper
Upper turms a string into its upper case representation.
$ docker inspect --format "{{upper .Name}}" container
