Artifactory CodeArtifact Migrator (ACM) is a tool which enables you to easily move all your artifacts from Artifactory to AWS CodeArtifact.

• Migrate packages individually either all versions or specify versions
• Migrate single or multiple repositories
• Migrate the entire Artifactory system
• Dryrun capabilities

ACM requires Python 3.7 or higher to run.

Using pipenv is the recommended way to install and run ACM.

Install the dependencies:

pipenv install

Install ACM:

pipenv run python setup.py install

Run ACM:

pipenv run artifactory-codeartifact-migrator -h

To simplify run operations, copy env.sh.template to env.sh, modify it per your settings, and then execute run.sh instead.

Alternatively, you can install the required dependencies natively with pip, and run the program using your locally installed python:

pip install -r requirements.txt
python setup.py install
artifactory-codeartifact-migrator -h

ACM can cache requests and publishing status for packages and repositories with the --cache option. This is handy in case there's communication issues. You will not have to start all over again with fetching packages and publishing and can just use the cache from the previous run.

For dryruns, acm-dryrun.db sqlite database will be used in the .replication folder.

For production runs, acm-prod.db sqlite database will be used in the .replication folder.

You can manage the databases manually with sqlite if you must.

If you have new packages added to Artifactory since the last run, and wish to refresh the cached packages that were fetched, use --refresh option.

If you wish to start over with a clean cache use the --clean option.

Options --refresh or --clean will not do anything without the --cache option set.

For a small amount of repositories, using the local sqlite caching is fine. However, if you're moving a lot of artifacts you may want to employ the power of DynamoDB for rapid i/o and other features. We've included an option you can use: --dynamodb which automatically creates DynamoDB tables on the same account your CodeArtifact exists. Keep in mind you should pay attention to permissions for the AWS account being used for the migrator.

If using --dryrun all DynamoDB options would happen on the following tables:

artifactory-codeartifact-migrator-dryrun-packages artifactory-codeartifact-migrator-dryrun-repositories

Otherwise, the production DynamoDB tables will be:

artifactory-codeartifact-migrator-prod-packages artifactory-codeartifact-migrator-prod-repositories

Keep in mind, the --dynamodb parameter will not work without the --cache parameter specified in command line.

ACM makes a lot of API calls to Artifactory and CodeArtifact.

We've included multi process option --procs to allow you to specify the number of processes to use for all API operations. We've tested this up to 100 processes so far successfully in a Kubernetes cluster and found the migration for millions of artifacts to go smoothly and quite fast.

There is also a known issue specifically with npm metadata. The way Artifactory handles package queries with npm, is that it locks mysql repeatedly for every single version of a package found. If there are a very large number of versions of that artifact it could cause delays.

This can mean searching and executing can take some time between packages.

For small repositories or specific package replication, an AWS session is fine. However, if you have a very large replication load you may find that the default AWS codeartifact token refresh may be impacted by your session expiration time. For those instances, it's recommended you use a service account with permanent access key, or a permament role for your instance or clusters to prevent such token generation from failing eventually.

If you have very large Artifactory repositories, and you are running this from a local system which uses VPN and expires every day or so, you may want to consider running this from a server unaffected by such restrictions.

If your Artifactory system is already in AWS EC2 or Kubernetes, it may pay for you to use a spot EC2 instance in AWS or even a Kubernetes cronjob and run the migrator there, as you don't pay for internal AWS traffic.

Want to contribute? Great!

We recommend using the --dryrun option to validate your code executes as desired and test on a real CodeArtifact instance for success.
