猪齿鱼pod出现ImagePullBackOff、ErrImagePull

Choerodon Installation management
#1

猪齿鱼主页面报网络异常，查看后台发现asgard报错
其他服务都无异常

[root@env]# kubectl  get pod -n c7n-system -w
choerodon-asgard-669c799f8d-bgjpm                    0/1     Init:ImagePullBackOff   0          3m36s

重启pod、删除pod都没有解决问题。。。
一下是pod的describe：

麻烦看一下该如何解决。

如下图镜像是存在的。请检查一下你的网络是否正常。

或者替换镜像地址：

helm upgrade choerodon-asgard c7n/choerodon-asgard \
    --reuse-values \
    --set plugins.skywalkingAgentImage=registry.hand-china.com/tools/skywalking-agent:6.6.0 \
    -n c7n-system \
    --version <version>

确实是因为这个原因导致的。
因为用的是公司内部服务器，不能访问外网。
所有的pod都会自动更新吗？
我不需要更新的话该如何设置？
