Migrate Mercurial (HG) to Git repository directly between remotes

Container to migrate from Mercurial repository into Git repository, directly between remotes via Docker container.

Mercurial --clone--> [This Container] --push--> Git

I developed this for my own use case but thought I'd share this.

Please test this yourself first - I hacked this up in a day so use at your own risk 😉 .

Dependencies

Basically a recent version of docker and docker-compose - developed with these:

• Docker >= 20.10.12
• docker-compose >= 1.29.2

Usage

1. Create your needs-specific docker-compose.yml (See docker-compose.yml.template for help)

   # Make a copy from template
   cp docker-compose.yml.template docker-compose.yml
   
   # Edit it to your needs
   vim docker-compose.yml

2. Run the migration container:

   ./run-hg-git-migration.sh

3. Profit 😋

To Develop

1. Create docker-compose.yml (see above)

2. Run this in special debug mode

   ./run-hg-git-migration.sh development

3. Get shell into container

   ./bash_shell-hg-git-migration.sh
