Today we celebrate the 32nd anniversary of our independence - the independence of Ukraine. A holiday of free people. A holiday of strong people. A holiday of people with dignity. A holiday of equals. Ukrainian men and women. All of them. In our entire country. This is a value for each of us. And this is what we are fighting for. And everyone is important in this fight. Because this is a fight for something that is important to everyone. An independent Ukraine. Happy Independence Day, Ukraine! Glory to Ukraine! πŸ‡ΊπŸ‡¦πŸ‡ΊπŸ‡¦πŸ‡ΊπŸ‡¦

kraken Kraken is a P2P-powered Docker registry that focuses on scalability and availability. It is designed for Docker image management, replication, and distribution in a hybrid cloud environment. With pluggable backend support, Kraken can easily integrate into existing Docker registry setups as the distribution layer. Kraken has been in production at Uber since early 2018. In our busiest cluster, Kraken distributes more than 1 million blobs per day, including 100k 1G+ blobs. At its peak production load, Kraken distributes 20K 100MB-1G blobs in under 30 sec. https://github.com/uber/kraken #docker #registry
