-
1:no resource found
解决办法
vim /etc/kubernetes/apiserver
找到KUBE_ADMISSION_CONTROL=这一行,去掉ServiceAccount,保存退出。 重启kube-apiservice服务即可

2:使用kubectl get pod命令查看pod时出现状态不对。
$ kubectl get pod NAME READY STATUS RESTARTS AGE mysql-j553h 0/1 ContainerCreating 0 1h
此时状态ContainerCreating是不正常的,应该是running。 按网上解决方法执行以下命令,会报找不到文件或文件夹
$ yum update $ yum install python-rhsm-certificates $ docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory.
感觉又跳进了一个坑,网上查了下说使用vpn下载镜像就可以解决(没试过),那没vpn的可以进行以下操作,首先把自己的镜像源更改成国内的
vim /etc/docker/daemon.json 修改 { "registry-mirrors": ["镜像地址(阿里加速器,自行申请)"] } $ sudo systemctl daemon-reload $ sudo systemctl restart docker
然后更新yum,手动安装rhsm和pod-infrastructure,
$ yum update $ yum search rhsm #搜索一下 $ yum install python-rhsm-certificates $ docker search pod-infrastructure #搜索一下国内源,有些下不了,找那些带有ok的下 INDEX NAME DESCRIPTION STARS OFFICIAL AUTOMATED docker.io docker.io/openshift/origin-pod The pod infrastructure image for OpenShift 3 8 docker.io docker.io/davinkevin/podcast-server Container around the Podcast-Server Applic... 5 docker.io docker.io/infrastructureascode/aws-cli Containerized AWS CLI on alpine to avoid r... 4 [OK] docker.io docker.io/newrelic/infrastructure Public image for New Relic Infrastructure. 4 docker.io docker.io/infrastructureascode/uwsgi uWSGI application server 2 [OK] docker.io docker.io/infrastructureascode/serf A tiny Docker image with HashiCorp Serf us... 1 [OK] docker.io docker.io/mosquitood/k8s-rhel7-pod-infrastructure 1 docker.io docker.io/podigg/podigg-lc-hobbit A HOBBIT dataset generator wrapper for PoDiGG 1 [OK] docker.io docker.io/stefanprodan/podinfo Kubernetes multi-arch pod info 1 docker.io docker.io/tianyebj/pod-infrastructure registry.access.redhat.com/rhel7/pod-infra... 1 docker.io docker.io/w564791/pod-infrastructure latest 1 docker.io docker.io/infrastructureascode/hello-world A tiny "Hello World" web server with a hea... 0 [OK] docker.io docker.io/jqka/pod-infrastructure redhat pod 0 [OK] docker.io docker.io/ocpqe/hello-pod Copy form docker.io/deshuai/hello-pod:latest 0
我找了个
$ docker pull docker.io/jqka/pod-infrastructure
把下载好的镜像标签该成registry.access.redhat.com/rhel7/pod-infrastructure:latest(刚才报错的那个名称)
$ docker tag docker.io/jqka/pod-infrastructure registry.access.redhat.com/rhel7/pod-infrastructure:latest
重启
systemctl restart kubelet
此时查看pods发现状态还是不对,莫急,可以把原来的rc删除,重新创建一个。 发现状态都正常了。
新手学习,步步为坑,记,共勉之
