Zhengcai Cloud, China's leading government procurement cloud service provider, has adopted @sealer_oss in overall #CloudNative on-premise business delivery in production. They also compared sealer with #Ansible and got the best practice.

See what @sealer_oss brings us, "Cluster Images: Achieve Efficient Distributed Application Delivery". This is a thorough introduction of sealer.

😼How about the new logo of @sealer_oss ? Actually we got inspired from the following 3 parts.
1. first letter of sealer
2. a box which is sealed hinting sealer's ability
3. does it look like </> ? sealer seals application and code 🌟😃

After two years of cooperation with ISVs in China, their business mostly on premise, We found that they can hardly try the CD tools currently in @CloudNativeFdn , like @fluxcd . Do we have plans to support on-premise CD scenarios?

👏🌟 Great news for @sealer_oss !!! The @CloudNativeFdn TOC have approved Sealer's application for Sandbox. Thank everyone for the work done for Sealer .

For what is a #Kubefile in @sealer_oss , please refer to the following guidance photo. One @sealer_oss command to build a cluster image with @kubernetesio and all applications included.

Introduce an open source #CloudNative tool Sealer . We learnt from #Dockerfile concept and create #Kubefile concept to isolate k8s and your distributed application into a single CloudImage😀😉🌟☀️
