为什么我的文件在 Linux 中不可读并出现路径错误？

Question

I am trying to install PGO (Postgres Operator) in k8s. I am following this documentation. At the 2nd step when I run following command

kubectl apply --server-side -k kustomize/install/default

I see error

master-k8s@masterk8s-virtual-machine:~/postgres-operator-examples-main$ kubectl apply --server-side -k kustomize/install/default
error: containers path is not of type []interface{} but map[string]interface {}

System Specifications:

• I have k8s 2 node cluster with one master node.
• All running Ubuntu 20.4

What I have try:

• I download repository again without clone and directory uploaded on master node

• I try to provide full path and this time I received the same error

• I checked the default directory there 2 files present

• I try to run this command inside the directory.

What Do I need?

I am looking for solution why I am not able to follow the 2nd step of document. Please help me to find what did I missed or doing it wrong.

I really thankful.

To fix your issue make sure kubectl integration like below:

As @Ralle commented, Check versions. Kustomize v2.1.0 and v3.0.0+, and is included in kubectl 1.21+ , for more information please look at the Kustomize doesn't work with CRDs when specifying images .

Update: The kustomize build flow at v2.0.3 was added to kubectl v1.14. The kustomize flow in kubectl remained frozen at v2.0.3 until kubectl v1.21, which updated it to v4.0.5 . It will be updated on a regular basis going forward, Check your versions & updates in the Kubernetes release notes.

For examples and guides for using the kubectl integration please see the kubernetes documentation .

Also check Kubernetes 1.22: Server Side Apply moves to GA for more information.
