⁠:whale: Available Docker image versions

⁠Rolling releaess

The following Docker image tags are rolling releases and are built and updated every night.

⁠:computer: Usage

⁠Display usage

$ docker run --rm cytopia/jsonlint --help

Usage: cytopia/jsonlint [-sti] <PATH-TO-FILE>
       cytopia/jsonlint [-sti] <GLOB-PATTERN>
       cytopia/jsonlint --version
       cytopia/jsonlint --help

 -s                 sort object keys
 -t CHAR            character(s) to use for indentation
 -i <GLOB-PATTERN>  Ignore glob pattern when using the GLOB-PATTERN for file search.
                    (e.g.: -i '\.terraform*.json')
                    Multiple ignores can be comma separated:
                    (e.g.: -i '\.terraform*.json,*test.json')
 <PATH-TO-FILE>     Path to file to validate
 <GLOB-PATTERN>     Glob pattern for recursive scanning. (e.g.: *\.json)
                    Anything that "find . -name '<GLOB-PATTERN>'" will take is valid.

⁠Check all JSON files and ignore .terraform/ directories

$ docker run --rm -v $(pwd):/data cytopia/jsonlint -t '  ' -i '*.terraform/*' *.json

⁠Check all JSON files for wrong indentation

This behaviour is achieved by saving the JSON with fixed indentation within the container in a different location and then applying a diff against the original file.

$ docker run --rm -v $(pwd):/data cytopia/jsonlint -t '  ' *.json

jsonlint -c  -t '  ' ./envs/dev/iam-permission/dev-policy.json
jsonlint -c  -t '  ' ./envs/dev/iam-permission/ops-policy.json
