在尝试使用SkyWalking官方文档在CentOS7的Kubernetes环境中快速启动套件时，遇到了一个bug。执行`makedeploy.kubernetes`命令后，docker返回错误，指出无法找到'exec: sh: executable file not found in $PATH'。问题出在Makefile的36行和62行，需要将sh更改为/bin/sh。修复此错误后，部署流程得以继续。

今天参照SkyWalking官方文档https://skywalking.apache.org/docs/skywalking-showcase/latest/readme/在centos7使用k8s快速启动一套环境

执行部署安装命令

make deploy.kubernetes

报错如下，应该是个bug

[root@node1 skywalking-showcase]# make deploy.kubernetes FEATURE_FLAGS=single-node
make[1]: 进入目录“/usr/local/src/skywalking-showcase/deploy/platform/kubernetes”
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "sh": executable file not found in $PATH: unknown.
error: no objects passed to apply
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "sh": executable file not found in $PATH: unknown.
error: no objects passed to apply

需要修改文件skywalking-showcase/deploy/platform/kubernetes/Makefile的36行和62行，将sh改为/bin/sh，改后如下

bhgedigital/envsubst /bin/sh -c "envsubst < /input" | kubectl -n $(NAMESPACE) apply -f - ; \  #36
bhgedigital/envsubst /bin/sh -c "envsubst < /input" | kubectl -n $(NAMESPACE) delete --ignore-not-found -f - ; \ # 62
