lite build : support to load offline images .

[fanux]

@lllwan lite build not support cache docker images now?

[lllwan]

Lite build already includes the ability of image cache. Why do you need to add it in local build?

[kakaZhou719]

Sorry for the unclear �description。i mean , could we support to import docker offline images and cache it directly?no need to run docker pull to fetch the desired images.

[lllwan]

fake docker pull request？

[kakaZhou719]

plugin : some application need to do post config after cluster running , while its hard for our plugin to support it.

for example: openebs cstor. it need to create CStorPoolCluster CRD when this application in production ready, and some parameter was generated by the operator like blockDeviceName.
https://github.com/alibaba/sealer/blob/main/applications/openebs/cstor/cspc.yaml

[fanux]

Do you have some idea about how to get blockDeviceName?

[fanux]

I think this is openebs design weakness, not friendly to deploy...

[clcc2019]

How about apply dragonfly to sealer?

[fanux]

dragonfly feature

rootfs robot need append subcommand to sealer ??

[fanux]

I think most user don't care about the robot, so needn't add it in sealer.

But robot should support containerd, v1.20+, ARM...

[fanux]

1. What is sealer roadmap?
2. maintainer rules?
3. docs/tech and docs/community
4. unit test plan

[fanux]

[myxxhui]

It would be perfect if Sealer could support base mirroring of GPU resources and sealer ClusterFile could designate some nodes as GPU nodes

[fanux]

COPY dir . dst is $rootfs/dir is better I think. = cp -r dir ./
COPY dirA ./dirB dst is $rootfs/dirB/dirA is better. = cp -r dirA ./dirB
COPY dirA /dirB dst is /dirB/dirA = cp -r dirA /dirB

[fanux]

• registry push

[fanux]

COPY ingress.tar /images

ACK-D:

1. 更好用的helm基础镜像 @kakaZhou719
2. 文档&官网建设 @bxy4543
3. Build模块重构，先写文档 @kakaZhou719
