The official offline installation method is too troublesome。

see: https://kubesphere.io/docs/installing-on-linux/introduction/air-gapped-installation/

what i want

1、online

curl -Ok https://kubesphere-installer.pek3b.qingstor.com/offline/v3.1.1/kubesphere-all-v3.1.1-offline-linux-amd64.tar.gz

---

2、offline tar -zxvf kubesphere-all-v3.1.1-offline-linux-amd64.tar.gz cd kubesphere-all-v3.1.1-offline-linux-amd64 ./kk install docker ./kk image push http://dockerhub.kubekey.local ./kk create cluster

what should do

1、add docker-20.10.7.tgz to kubesphere-all-v3.1.1-offline-linux-amd64.tar.gz

2、offline install docker is easy

docker_version=19.03.5
curl -Lo docker.tgz https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/docker-${docker_version}.tgz
tar -xvzf docker.tgz -C /usr/bin --strip=1

1、about docker: you can install with binary like sealer: https://github.com/alibaba/sealer/blob/c7bb9433848b7e0c993a545e315518f24095ae1f/filesystem/rootfs/docker/scripts/docker.sh

2、about docker registry: user must give a registry url ，push image to that registry, or give a guide for user to install a registry， or let user prepare one node for harbor or registry install

3、nothing else need to do，real offline install for product environment

hi @willzhang , thanks for your detailed proposal. That's great.

[pixiake]

Thanks for your proposal, we have received some similar demands before. At present, we are refining for offline environment.

./kk init registry -h

kk can run a registry for deploy use?

Hi all! The new KubeKey v2.0.0-alpha.3 has a new way to offline install clusters easily. Welcome to try and feel free to give us some suggestions.

/need-to-verify

Please see the new doc: https://github.com/kubesphere/kubekey/blob/master/docs/zh/manifest_and_artifact.md

[willzhang]

it waste a lot of time to generate artifact，and install many thing and face many problems , if support a standerd package kubesphere-all-v3.2.1-offline-linux-amd64.tar.gz for user will be good.
