Mirroring large number of GitHub or Bitbucket repositories
#

Use case:

I want to create local clone of a large number of repositories from an organization in GitHub / Bitbucket.

Assumptions
#

user has SSH key registered with the GH / BB - can clone using ssh protocol
user has successfully cloned at least one repo from command line before (the /etc/hosts contains host entries for BB and GH)
user has modern version of Python 3 installed (3.6 or better)
user has local installation of a reasonably modern Git

Steps
#

First I use the ./bb-repo-links.sh and ./gh-repo-links.sh to generate list of repositories. See these blog articles: How to list repositories in Bitbucket and How to list repositories in github

These are text files and have the structure like this:

EXFO|git@bitbucket.org:thinkwrap/exfo-tw-docker-jenkins.git
FARO|git@bitbucket.org:thinkwrap/faro-infrastructure.git
H3|git@bitbucket.org:thinkwrap/headless-api-gateway.git
H3|git@bitbucket.org:thinkwrap/headless-cart-service.git
H3|git@bitbucket.org:thinkwrap/headless-catalog-service.git
H3|git@bitbucket.org:thinkwrap/headless-connector-atg.git
H3|git@bitbucket.org:thinkwrap/headless-connector-contentful.git

The first field is the project prefix, and the second is the SSH url for cloning the repository. They are separated by the | character.

Cloning is trivial:

python3 ./process_repos.py NAME-OF-THE-CONTROL-FILE ....

e.g.

python3 ./process_repos.py pivotree_h3.bb-repo2 pvtrlabs.gh-repo

The Python script uses ../MIRROR as the starting point for the mirrored tree.

This can be changed by exporting the variable MIRROR_ROOT

export MIRROR_ROOT = '../MIRROR2'

The generated structure looks like this:

PLAFORM > ACCOUNT > PROJECT > REPO

where:

PLATFORM is bitbucket.org or github.com
Account is organization name within the platform
PROJECT is project name for Bitbucket, defaults to ‘src’ for GitHub
REPO is the repository name

NOTE: the names of some projects are < edited >.

Updating
#

If the Python script encounters an existing repository, it tries to do an update by fetching the remote updates. It does NOT merge.
