One command to build multi-clusters by karmada helm chart
What would you like to be added:
A script using just one command to build multi-clusters by karmada helm chart
Why is this needed:
There are sevaral scenarios:
1) scenario one
I am a real user of karmada, I has several real clusters in prod environment, I want to build multi-clusters by karmada.
It is not fit for me to use hack/local-up-karmada.sh, it just mocked some KinD clusters.
I tend to install karmada by helm chart on given clusters, so I should install karmada on control plane and then join member clusters. But it is so hard for me to finish the whole process, especially in pull mode, I have to settle the certs of karmada-agent.
I want just one command to finish the whole process, I need just provided my kubeconfig path and specify how many clusters I want, after one command, the whole clusters builded success, just like:
NAME VERSION MODE READY AGE APIENDPOINT
member1 v1.27.3 Push True 45s https://172.18.0.3:6443
member2 v1.27.3 Pull True 2s
member3 v1.27.3 Push True 41s https://172.18.0.4:6443
2) scenario two
I am new to Karmada, I want to try karmada, I am familiar with helm chart.
I just want to try the features of karmada, I don't have any patience for karmada installation.
I want just one command script to help me create clusters first and then build the control plane and member cluster success.
Besides, I am behind firewall, pulling images is a trouble to me when installing, I don't want to waste time to solve it by config proxy, I can only accept fetch the image to local node in advance.
3) scenario true
I am a Developer or Tester, our project is based on Karmada, I want to construct a variety of complex multi-cluster scenarios.
So, I want a installation script which can specify the number of push mode clusters or pull mode clusters.
For example, I need 5 push mode clusters and 3 pull mode clusters, by executing one command, the member clusters installed success.
One command to build multi-clusters by karmada helm chart
Why not use karmadactl init?
Why not use karmadactl init?
supposing I have 10 cluster, I want to install karmada control plane at No.1 cluster, and join push mode member cluster at No.2 ~ No.5 cluster, and join pull mode member cluster at No.6 ~ No.10 cluster, however karmadactl neither can achieve one command to build multi-cluster, the user should execute the command step by step.
besides, some user tend to use helm, since we provided this install method, why not improve it.
besides, I often hear users feedback the failure, even diss the helm installtion method in wechat group, it actually not friendly using to users.
duplicate #4306
thanks for finding~ There was a problem with the network and duplicate submissions were made
scenario one
I don't think the script is the official tooling for users to install Karmada in a production scenario.
scenario two I am new to Karmada, I want to try karmada, I am familiar with helm chart.
In this case, the developer can go with the recommended quick start guide which is the community maintains for developers.
- scenario true I am a Developer or Tester, our project is based on Karmada, I want to construct a variety of complex multi-cluster scenarios. So, I want a installation script which can specify the number of push mode clusters or pull mode clusters.
This is not a real-world use case, Karmada installation and cluster registration are different operations.
