- George relishes complexity. Nobody understands how the system works... apart from him.
- QWERTY 3.0 is a disaster, 2 years late
- Docker Hub is Docker’s cloud service for … Publishing and discovering container images through the public registry Team collaboration and automation of application workflows
- However you look at it, the growth has been extraordinary. Almost a quarter million users … … who have created or are collaborating on 150,000 repositories … … X% of which are publicly available … … serving more than Y TB of Docker container images … There are millions of consumers of these repos, and altogether they have pulled them more than 500 million times … … using Z TB of bandwidth.
- … also launched at DockerCon last June, the Docker Hub Official Repos program has grown to almost 80 Official Repos. These curated images are actively maintained by the upstream owners or by Docker … … and have proven to be some of the most popular repositories on Docker Hub …
- Many of you are probably aware of our open source Registry v2 efforts, which shipped in April. The Registry v2 team has been working hard with the Docker Hub team to transition the Docker Hub Registry to Registry v2. New CDN optimization The results have been simply outstanding. First … the new Docker Hub is FASTER. This is a result of the v2 protocol being dramatically more efficient than v1, requiring 80% fewer requests and 60% less bandwidth to accomplish the same pull. FEWER REQUESTS parallel pulls of multiple layers fewer requests, and the requests that are being done are done in parallel LESS BANDWIDTH less bandwidth required due to better caching (better cacheability) and sharing across images
- Third … thanks to completely re-built backend and frontend stacks, Docker Hub has a much more responsive user experience. The user’s Dashboard is … The search results is …
- Second … the new Docker Hub is more reliable than previously. This is the result of improved reliability of the Registry v2 protocol. Specifically, Docker Hub Registry v2 has an authentication stack independent of other Hub services. This gives push / pull operations improved availability. User benefit: less interruptions of pulls … and Docker uses Docker Hub Why more reliable? Fewer requests Web transaction is a simpler protocol and thus less error-prone
- … with features critical for on-premise deployments If you’re an OSS registry user … EASY install, update, rollback
- … and to make all this easy to configure and manage, Docker Trusted Registry also features a web-based admin GUI … for insights into the state of the DTR host …
