Repo for CapRover One Click Apps


  • Find/create a docker-compose file for the one click app
  • Convert yaml file to json
  • Copy the content into the one click ap structure. See this for the reference: wordpress.json
  • Variables are prefixed with $$cap
  • There is one special variable called $$cap_appname which exists for all oneclick apps
  • Varibles can be anywhere in the JSON and they will be replaced by what user enters
  • Each variable must have id, label. It may also have defaultValue, validRegex, description.
  • Other than image, environment, ports, volumes, depends_on, other parameters are ignored. Make sure they are not important.
  • Instead of image in a service, you can use dockerfileLines which is an array of strings.
  • Some webapps, use a non-standard HTTP port. For example, Adminer's Docker image uses port 8080. In this case, add containerHttpPort to the service. See adminer.json for example.
