Tiny Alpine-based multistage-build dockerized version of jsonlint[1], which adds additional functionality such as failure on wrong indentation, lint multiple files via wildcard search and being able to ignore files via wildcards. The image is built nightly against multiple stable versions and pushed to Dockerhub.

Point in time releases

The following Docker image tags are built once and can be used for reproducible builds. Its version never changes so you will have to update tags in your pipelines from time to time in order to stay up-to-date.

πŸ“‚ Docker mounts

The working directory inside the Docker container is /data/ and should be mounted locally to where your JSON files are located.

πŸ’» 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
