This docker image is creating a fake git repository with fake commits in the past.
This is useful, if you need an example repository for scientific research.
Run a bash inside the container. If you want to push the fake repository, you
will probably mount your .ssh credentials.
docker run -it --rm -v /home/user/.ssh:/home/uid1000/.ssh thomass/git-commit-generator bash
Inside the container execute the
create-commits. This will result in a new
fake repository with fake commits. Enter
git log in the repository directory
/tmp/... to watch them.
add initial data
Mount the initial data to the
/workspace directory inside the container.
docker run -it --rm \ -v /path/to/local/data:/workspace \ ...
You can run the script with preceeding environment variables like:
MIN_MOD_LINEAR='+3600' MAX_MOD_LINEAR='+3600' create-commits
Following variables are available
|FIRST_COMMIT_SINCE||31536000 (1 year ago)||The seconds passed since the first commit.|
|LAST_COMMIT_SINCE||0 (now)||The seconds passed since the last commit.|
|MIN_SHIFT||10||The initial minimum distance between two commits.|
|MAX_SHIFT||86400 (1 day)||The initial maximum distance between two commits.|
|MIN_MOD_LINEAR||'+0'||The seconds added (+) or removed (-) to/from MIN_SHIFT after every commit.|
|MAX_MOD_LINEAR||'+0'||The seconds added (+) or removed (-) to/from MAX_SHIFT after every commit.|
|MIN_MOD_FACTOR||1||The factor MIN_SHIFT is modified after every commit.|
|MAX_MOD_FACTOR||1||The factor Max_SHIFT is modified after every commit.|
variable commits for paths
You can create a different commit behavior for different paths within your repository.
The paths must exist within the workspace. To do so:
Create a file with two columns separated by semicolon where the first column is
the path and the second column a value between 0 and 10000:
/path/to/somewhere;8000 /other/path/to/anywhere:4000 /third/path/example;9500
Pass this file to the
create-commits command (behind).
After every commit to the root of the repository a number between 1 and 10000 is
randomly chosen. If the number in your file behind each path is greater than the
random number, also a commit to this path is made.
The lower limit can be modified after every turn:
|PATH_MOD_LINEAR||0||This number is added after each round to the lower limit.|
|PATH_MOD_FACTOR||1||After each round the lower limit is multiplied by this number.|
PATH_MOD_FACTOR=1.01 PATH_MOD_LINEAR=3 create-commits /workspace/commit_paths.txt
Here are three example repositories with different settings. You can watch the commit history and commit graph there.
