ssh key 配置
進入容器生成新的ssh key
[root@localhost mytest]# docker exec -it jenkins bash
jenkins@790140a70e6f:/$ cd /var/jenkins_home/
jenkins@790140a70e6f:~$ ssh-keygen -t rsa -C "wangyuhao01@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/var/jenkins_home/.ssh/id_rsa):
Created directory '/var/jenkins_home/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /var/jenkins_home/.ssh/id_rsa
Your public key has been saved in /var/jenkins_home/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:LJt2FmYqJFN6fUrn64TtXPgOTigPKLVwLwFJjNK+5Wo wangyuhao01@longfor.com
The key's randomart image is:
+---[RSA 3072]----+

[root@localhost data]# cd .ssh/

進入容器現(xiàn)在執(zhí)行下如下命令，否則直接使用ssh key 會報錯：
[root@localhost mytest]# docker exec -it jenkins bash
jenkins@790140a70e6f:/$ git ls-remote -h -- git@gitee.com:xiaolyuh/test.git HEAD
The authenticity of host 'gitee.com (212.64.63.190)' can't be established.
ECDSA key fingerprint is SHA256:FQGC9Kn/eye1W8icdBgrQp+KkGYoFgbVr17bmjey0Wc.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'gitee.com,212.64.63.190' (ECDSA) to the list of known hosts.
將公鑰配id_rsa.pub置到gitlab，私鑰id_rsa配置到j(luò)enkins全局憑據(jù).

執(zhí)行構(gòu)建&查看日志

通過日志我們可以發(fā)現(xiàn)jenkins將代碼拉取到了/var/jenkins_home/workspace/mytest1目錄，/var/jenkins_home/目錄我們已經(jīng)映射到了宿主機的/usr/local/docker/jenkins/data目錄，到這個目錄我們可以看到已經(jīng)拉取下來后的文件篷就。

配置Maven構(gòu)建代碼
將安裝好的maven和jdk映射到j(luò)enkins容器的數(shù)據(jù)卷中
mv /usr/local/maven/ /usr/local/docker/jenkins/data/
mv jdk1.8.0_361/ /usr/local/docker/jenkins/data/jdk
映射好后，我們可以到j(luò)enkins容器中的home目錄查看到maven和jdk近忙。

新增Docker打包和啟動所需的配置
image.png
在項目下新增docker文件夾，然后新增Dockerfile和docker-compose.yml文件
增加Dockerfile文件
# 設(shè)置依賴鏡像
FROM daocloud.io/library/java:8u40-jdk
# 拷貝jar到容器工作目錄
WORKDIR /usr/local/docker
COPY ./app.jar /usr/local/docker
# 啟動jar文件
CMD java -jar app.jar
增加docker-compose.yml文件
version: "3.1"
services:
mytest:
# 通過當(dāng)前目錄下的Dockerfile來構(gòu)建鏡像
build:
context: ./
dockerfile: Dockerfile
image: mytest:v1.0.0
container_name: mytest
ports:
# 將容器80端口映射到宿主機80端口映上
- 8081:80
配置單個任務(wù)的Publish

命令解釋
# 切換到上傳后的docker
cd /root/docker
# 刪除原有jar包
rm -rf app.jar
# 將新的jar包拷貝到docker目錄
mv ../spring-boot-student-devops/target/*.jar app.jar
# 刪除無效目錄
rm -rf ../spring-boot-student-devops
# 通過docker-compose進行打包和啟動容器
docker-compose down
docker-compose up -d --build
# 刪除所有未打標(biāo)簽的鏡像
docker rmi $(docker images -q -f dangling=true)
執(zhí)行任務(wù)構(gòu)建&日志

這里傳輸了3個文件
