🔒 Local HTTPS Proxy

This simple docker setup allows you to access a domain via https which is internally proxied to your localhost at a specific port number

For example, you can access:

https://local.kultmedia.com

and see the content that is being served by:

http://localhost:7008

This can be useful when using tools like Resource Override to avoid CORS errors and other SSL issues

Variables

The project uses some variables that can be customized inside Dockerfile.

Here is the recap:

Variable Name	Description	Default value
CUSTOM_PORT	This is the port where your localhost service is running	7008
CUSTOM_DOMAIN	This is the domain that you will access via https	local.kultmedia.com

How to use

Create the certificates

To have https working correctly, you will need to generate the certificates from your machine

• Install mkcert on your machine
• Run mkcert -install
• Now move into the certs folder of this project
• Run mkcert local.kultmedia.com (if you customized the domain, use your custom one)
• If the command worked correctly you should have two new files:
  • local.kultmedia.com.pem
  • local.kultmedia.com-key.pem
• If, for some reasons, the two files are not named like this, rename them as above
  • In case you customized the domain, the certificates need to be renamed accordingly

Running the Docker image

• Make sure that Docker is installed and running
• Run with docker-compose up --build

Done 🎉

• Launch the service running at the port configured in CUSTOM_PORT (7008 is the default)
• Now access https://local.kultmedia.com

Extra stuff

Using a custom domain

If you use the default domain (local.kultmedia.com) you don't need to do anything else, since this domain is already pointing to localhost. However, if you want to use a custom domain, you also need to make sure that this domain resolves locally to localhost. In macOS this is done by editing the hosts file:

sudo nano /etc/hosts

Now, assuming that your domain is dummydomain.local.dev, add this line:

127.0.0.1       dummydomain.local.dev

Make sure to save the file. Now the domain will resolve to localhost.
