When contributing to this repository, please first discuss the change you wish to make via issue, email, or any other method with the owners of this repository before making a change. The best way is our Slack channel (link at the footer of CapRover.com)
Please note we have a code of conduct, please follow it in all your interactions with the project.
Since the birth of CapRover, there has been many contributions and suggestions that shaped CapRover as we know it today. One of the very important factor in the contribution you make is to stick with CapRover design philosophy.- CapRover is not an enterprise grade application like Kubernetes. Do not patch it with half-done features that make it look like one - it will eventually fail as we don't have resources to support such features.- CapRover scope is a helper around Docker, nginx and Let's Encrypt. If a new feature is doable via the existing features, or a basic tool, do not add it to CapRover. We do not want to bloat this application. One example is: "Add a flag to customize the placement constraints of containers". This is definitely doable in Docker, but we don't want to mirror every single functionality of Docker to CapRover. If we do that, CapRover becomes a very hard to maintain project. Instead we should add customization hooks for these advanced and rare use cases. For example, instead of mirroring every single nginx config, we added the ability of customizing the nginx config for advanced users.- Last but not least AVOID LARGE PULL REQUESTS at all cost as they won't get reviewed unless they are discussed in the Slack channel beforehand.
- IF APPLICABLE: Update the docs (https://github.com/caprover/caprover-website) with details of changes to the interface, this includes new environment variables, exposed ports, useful file locations and container parameters.
- Make sure your commit comments are self explanatory.
- Discuss the changes you want to make beforehand.
- Please avoid making opinion-based changes if it's just a code-style change - this includes, but not limited to, changes to how we work with promises, class inheritence and etc.
- To keep the process simple with just a few contributors, development happens directly on the master branch and releases will be deployed on the same branch.
- By creating a Pull Request, you agree to all terms in https://github.com/caprover/caprover/blob/master/contrib.md
First, you need a Captain instance running in debug mode, this can be a remote server, a VM on your local machine, or your local machine itself. Needless to say, Docker is required (same minimum version as mentioned in README). Ubuntu is the best dev environment for CapRover.
Docker for Mac users: You need to add
/captainto shared paths.
To do so, click on the Docker icon -> Preferences -> File Sharing and add/captain
Log in to your machine, clone the git repo, go to app-backend directory and run the following lines:
$ npm install
$ ./dev-scripts/dev-clean-run-as-dev.shYou are good to go! You can run the following line to see the logs for the back-end service.
npm run devThe main differences between the release and debug mode are:
- docker image is created from the local source file, instead of getting pulled from Docker hub
- security is much weaker is debug due to a static salt
- self health monitoring is disabled in debug so that we can see possible crashes
- same origin policy is disabled in debug mode to make front end development easier
- an additional endpoint is available at
/force-exitwhich force restarts the backend service - static resources (including front end app) are not being served in debug build.
Captain by default uses captain.localhost as its root domain. It's not always needed, but if you need a root
domain for your development, you can simply run a local DNS server on your local machine and point
*.captain.localhost (wild card domain) to your local IP. A simple hosts change won't be useful as we need a wildcard entry.
On ubuntu 16, it's as simple of editing this file:
/etc/NetworkManager/dnsmasq.d/dnsmasq-localhost.conf (create if does not exist)
And add this line to it: address=/captain.localhost/192.168.1.2 where 192.168.1.2 is your local IP address.
To make sure you have dnsmasq, you can run which dnsmasq on your terminal, if it's available,
path of it will be printed on the terminal, otherwise, there won't be anything printed on your terminal.
See https://github.com/caprover/caprover-frontend
See https://github.com/caprover/caprover-cli
Start the debug build for the backend service as explained above. To see any changes you make,
first save the changes, then you need to restart the service either by sending a request to /force-exit endpoint,
or by running npm run dev.
Security issues are high priority and they will be addressed immediately. If you find a security issue, please do not post as a public issue, instead, please email it to us: security at caprover dot com.
