Github操作使用Maven构建jar并用于docker镜像构建

时间：2019-11-26 08:18:53

标签： maven docker github yaml github-actions

我希望git push应该触发mvn clean package并使用构建jar构建docker映像。 可悲的是，我在图像创建时出现以下错误

Step 2/4 : ADD target/de-sy-file.jar de-sy-file.jar
ADD failed: stat /var/lib/docker/tmp/docker-builder601875986/target/de-sy-file.jar: no such file or directory
##[error]Process completed with exit code 1.

有人可以告诉我在哪里找到内置罐子吗？

我找到了下载和上传工件的解决方案。

我的新action.yml：

# This workflow will build and push a new container image to Amazon ECR,
# and then will deploy a new task definition to Amazon ECS, on every push
# to the master branch.
#
# To use this workflow, you will need to complete the following set-up steps:
#
# 1. Create an ECR repository to store your images.
#    For example: `aws ecr create-repository --repository-name my-ecr-repo --region us-east-2`.
#    Replace the value of `ECR_REPOSITORY` in the workflow below with your repository's name.
#    Replace the value of `aws-region` in the workflow below with your repository's region.
#
# 2. Create an ECS task definition, an ECS cluster, and an ECS service.
#    For example, follow the Getting Started guide on the ECS console:
#      https://us-east-2.console.aws.amazon.com/ecs/home?region=us-east-2#/firstRun
#    Replace the values for `service` and `cluster` in the workflow below with your service and cluster names.
#
# 3. Store your ECS task definition as a JSON file in your repository.
#    The format should follow the output of `aws ecs register-task-definition --generate-cli-skeleton`.
#    Replace the value of `task-definition` in the workflow below with your JSON file's name.
#    Replace the value of `container-name` in the workflow below with the name of the container
#    in the `containerDefinitions` section of the task definition.
#
# 4. Store an IAM user access key in GitHub Actions secrets named `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`.
#    See the documentation for each action used below for the recommended IAM policies for this IAM user,
#    and best practices on handling the access key credentials.

我将解释一个复杂但可能不理想的解决方案。

假设我有一个看起来像这样的多模块Maven项目

│
├── cluster
│   ├── Dockerfile
│   ├── pom.xml
│   ├── src
│   └── target
│
├── common
│   ├── pom.xml
│   ├── src
│   └── target
│
├── loadbalancer
│   ├── Dockerfile
│   ├── pom.xml
│   ├── src
│   └── target
│
└── pom.xml

此Maven项目生成两个JAR应用程序，一个loadbalancer应用程序和cluster应用程序。我要做的是为这两个JAR应用创建两个不同的图像。

在设置我的GitHub Action之前，我将先运行

mvn clean install
docker build -t myimage/loadbalancer:latest ./loadbalancer
docker build -t myimage/cluster_node:latest ./cluster

第一个命令将在loadbalancer/target/和cluster/target/中生成我的JAR，然后通过构建这两个Dockerfile s将这些JAR文件放入docker映像中< / p> 

FROM fabric8/java-alpine-openjdk11-jre
WORKDIR /usr/src/app
COPY target/cluster.jar ./cluster.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "cluster.jar"]

FROM fabric8/java-alpine-openjdk11-jre
WORKDIR /usr/src/app
COPY target/loadbalancer.jar ./loadbalancer.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "loadbalancer.jar"]

这就是您在本地计算机上所需的全部内容。

所有这些最好的部分是您可以使用GitHub Actions完全做到这一点（但是可能会有更好的方法来对Maven项目进行docker化），这是一个GitHub Action：

  1. 测试并构建loadbalancer.jar和cluster.jar

  2. 使用这些新生成的.jar s构建两个Docker映像

  3. 为每个图像添加两个不同的标签：

    a。 latest

    b。触发此操作的提交的8位数字

  4. 将它们推送到新发布的GitHub Container Registry

工件应该已经存储在临时工作区中，因此您不必上传/下载。
