bat-alpine
a docker file to build an image of bat based on alpine
The image built from this Dockerfile is on dockerhub:
docker pull tabroughton/docker-alpine
bat is a syntax highlighting replacement for linux cat developed by Dan Lynn: https://github.com/sharkdp/bat
There is a Docker image from bat developer currently based on ubuntu (~260MB image) whereas this image is based on Alpine (creates ~30MB image) that you can use to run bat in a container:
Once image is built:
alias bat='docker run -it --rm -e BAT_THEME -e BAT_STYLE -e BAT_TABS -v "$(pwd):/myapp" tabroughton/bat-alpine'
Now when you run: bat myfile the output to the terminal is the contents of myfile formatted with syntax highlighting, line numbers, etc.
Before using it would be worth checking https://hub.docker.com/r/danlynn/ to see if the maintainer of bat has created a more recent (more official) alpine based image.
