一.net core 自动化发布到docker （Jenkins安装）

1.安装Jenkins

参考资料:https://www.jenkins.io/doc/book/installing/docker/#downloading-and-running-jenkins-in-docker

1.Open up a terminal window.(打开一个终端窗口。)

2.Create a bridge network in Docker using the following docker network create command:(使用以下Docker network Create命令在Docker中创建桥接网络)

3.In order to execute Docker commands inside Jenkins nodes, download and run the docker:dind Docker image using the following docker run command:(为了在Jenkins节点内执行Docker命令，请使用以下dockerrun命令下载并运行Docker:dind-Docker映像)

4.获取Jenkins镜像

4.1：Customize the official Jenkins Docker image, by executing the following two steps:Create a Dockerfile with the following content:

4.2：Build a new docker image from this Dockerfile, and assign the image a meaningful name, such as "myjenkins-blueocean:2.401.3-1":

cd 刚才创建Dockerfile目录下执行：来创建镜像

5. Run your own myjenkins-blueocean:2.401.3-1 image as a container in Docker using the following docker run command:（使用以下Docker Run命令在Docker中运行您自己的myjenkins-blueocean:2.401-3-1映像作为容器：）

本篇文章只安装了Jenkins

docker network create jenkins

3.In order to execute Docker commands inside Jenkins nodes, download and run the docker:dind Docker image using the following docker run command:(为了在Jenkins节点内执行Docker命令，请使用以下dockerrun命令下载并运行Docker:dind-Docker映像)

docker run \
  --name jenkins-docker \
  --rm \
  --detach \
  --privileged \
  --network jenkins \
  --network-alias docker \
  --env DOCKER_TLS_CERTDIR=/certs \
  --volume jenkins-docker-certs:/certs/client \
  --volume jenkins-data:/var/jenkins_home \
  --publish 2376:2376 \
  docker:dind \
  --storage-driver overlay2

If you have problems copying and pasting the above command snippet, use the annotation-free version below:(如果您在复制和粘贴上面的命令片段时遇到问题，请使用下面的无注释版本)

docker run --name jenkins-docker --rm --detach \
  --privileged --network jenkins --network-alias docker \
  --env DOCKER_TLS_CERTDIR=/certs \
  --volume jenkins-docker-certs:/certs/client \
  --volume jenkins-data:/var/jenkins_home \
  --publish 2376:2376 \
  docker:dind --storage-driver overlay2

会自动拉取镜像

docker:dind

解释一下这个：可以自行百度

有时需要在容器内执行 docker 命令，比如：在 jenkins 容器内运行 docker 命令执行构建镜像
直接在 docker 容器内嵌套安装 docker 未免太过臃肿
更好的办法是：容器内仅部署 docker 命令行工具（作为客户端），实际执行交由宿主机内的 docker-engine（服务器）

4.获取Jenkins镜像

4.1：Customize the official Jenkins Docker image, by executing the following two steps:Create a Dockerfile with the following content:

(通过执行以下两个步骤自定义Jenkins Docker的官方镜像：创建一个包含以下内容的Dockerfile)

创建Dockerfile-内容：

FROM jenkins/jenkins:2.401.3-jdk17
USER root
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
  https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
  signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
  https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean docker-workflow"

4.2：Build a new docker image from this Dockerfile, and assign the image a meaningful name, such as "myjenkins-blueocean:2.401.3-1":

（从这个Dockerfile构建一个新的docker映像，并为该映像指定一个有意义的名称，例如“myjenkinsblueocean:2.401-3-1”）

cd 刚才创建Dockerfile目录下执行：来创建镜像

docker build -t myjenkins-blueocean:2.401.3-1 .

If you have not yet downloaded the official Jenkins Docker image, the above process automatically downloads it for you.（如果您还没有下载Jenkins Docker的官方镜像，上述过程会自动为您下载-因为dockerfile里面写了拉取地址）

5. Run your own `myjenkins-blueocean:2.401.3-1` image as a container in Docker using the following docker run command:（使用以下Docker Run命令在Docker中运行您自己的myjenkins-blueocean:2.401-3-1映像作为容器：）

docker run \
  --name jenkins-blueocean \
  --restart=on-failure \
  --detach \
  --network jenkins \
  --env DOCKER_HOST=tcp://docker:2376 \
  --env DOCKER_CERT_PATH=/certs/client \
  --env DOCKER_TLS_VERIFY=1 \
  --publish 8080:8080 \
  --publish 50000:50000 \
  --volume jenkins-data:/var/jenkins_home \
  --volume jenkins-docker-certs:/certs/client:ro \
  myjenkins-blueocean:2.401.3-1

If you have problems copying and pasting the command snippet, use the annotation-free version below:（如果在复制和粘贴命令片段时遇到问题，请使用下面的无注释版本：）

docker run --name jenkins-blueocean --restart=on-failure --detach \
  --network jenkins --env DOCKER_HOST=tcp://docker:2376 \
  --env DOCKER_CERT_PATH=/certs/client --env DOCKER_TLS_VERIFY=1 \
  --publish 8080:8080 --publish 50000:50000 \
  --volume jenkins-data:/var/jenkins_home \
  --volume jenkins-docker-certs:/certs/client:ro \
  myjenkins-blueocean:2.401.3-1
