  • devops 自定义jenkins agent node docker build 异常

谢谢那个问题解决了 但是k8s构建镜像的时候 报错envsubst: not found + kubectl apply -f -是为什么 我手动用kubectl命令是能构建的

[upl-image-preview url=

]

以下是我构建node18镜像时候的脚本

Dockerfile:

FROM node:18.13.0

LABEL maintainer=“Bibin Wilson bibinwilsonn@gmail.com”

COPY ./test.sh /data/nodes/test.sh

RUN /data/nodes/test.sh

CMD [“docker”,“version”]

shell:

curl -f https://download.docker.com/linux/static/stable/x86_64/docker-18.09.9.tgz | tar xvz && \

mv docker/docker /usr/bin/ && \

rm -rf docker

curl -f https://get.helm.sh/helm-v2.11.0-linux-amd64.tar.gz | tar xzv && \

mv linux-amd64/helm /usr/bin/ && \

mv linux-amd64/tiller /usr/bin/ && \

rm -rf linux-amd64

curl -f https://get.helm.sh/helm-v3.5.0-linux-amd64.tar.gz | tar xzv && \

mv linux-amd64/helm /usr/bin/helm3 && \

rm -rf linux-amd64

curl -f -LO https://storage.googleapis.com/kubernetes-release/release/v1.26.1/bin/linux/amd64/kubectl && \

chmod +x kubectl && \

mv kubectl /usr/bin/

curl -fL https://github.com/kubesphere-sigs/ks/releases/download/v0.0.64/ks-linux-amd64.tar.gz | tar xzv && \

mv ks /usr/bin/

curl -fL https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize%2Fv4.5.3/kustomize_v4.5.3_linux_amd64.tar.gz | tar xzv && \

mv kustomize /usr/bin/

    chilianyi 基于nodejs 去构建的 需要基于base 么 如果基于base的话那我还可以使用nodejs的功能么

      chilianyi 我刚试了一下基于base自定义node18的镜像还是不

      [upl-image-preview url=

      ]

      构建镜像脚本：

        # docker run -it kubespheredev/builder-base:v3.1.0 envsubst -V

        我试了下，原生带的。 你用这个 配置，casc 对应 configmap 里找到对应的 image id，进去看下，有 envsubst 这个 命令吗

          qweqe417 我试了下这个 image，是没有装 envsubst

          docker run --network=host -it node:18.13.0 bash

          你可以试试在 Dockerfile 中，装上这个 gettext-base

              chilianyi 谢谢指点 解决了，不过有个建议 如果您是官方人员建议把自定义agent 的那个文档补充完整一些，按照你们现在那个文档来，自定义镜像那块好多不确定的点，我一路踩了好多坑。

                  yongpanyan 是否要基于 base 镜像，可以自己决定；base 镜像安装了一些命令，如果不基于 base 镜像，自己需要的命令需要在自定义的镜像里安装；
