使用NodeJ和sed创建新的Kubernetes配置文件时出错

Question

I am using the Shelljs and sed command to generate the new K8S config file

shell.exec(`sed -e s%${server}%${endpoint}%g -e s%${certificate}%${cert}%g config-temp`)
shell.exec("cat config-temp | tee config")

Then I am checking if the K8S cluster is working by running

kubectl cluster-info

The error message looks like

error: Error loading config file "~/.kube/config": yaml: control characters are not allowed

However, if I copy all the content from the config-temp , then paste it into the config , kubectl cluster-info works.

I haven't found same error messages above online. I am just wondering if anyone come across the similar issue. Any helpers

Answer 1

尝试使用sed -Ei而不是sed -e ，真正编辑config-temp

Answer 2

Thanks for you guys input. the sed part has no problem, I guess I haven't phased my problem clear enough. The problem is when I replace the certificate with cert, the text in the cert variable has some special characters , which cannot be recognized by K8S.
