我有一个看起来像这样的构建过程:
1.代码被推送到由BitBucker管道拾取的BitBucket
image: node:8.2.1
pipelines:
default:
- step:
name: Push Server to AWS Repository
script:
- docker login -u AWS -p $AWS_ECR_LOGIN https://$AWS_ECR_URL
- docker build -t dev .
- docker tag dev:latest $AWS_ECR_URL/dev:latest
- docker push $AWS_ECR_URL/dev:latest
options:
docker: true
2. BitBucket管道从repo中的Dockerfile构建Docker镜像并将其推送到Amazon ECR
# BUILD DEV IMAGE and TEST
FROM node:8.2.1 as builder
COPY ./ /user/src/app
WORKDIR /user/src/app
RUN npm install -g grunt-cli --quiet
RUN npm install --quiet
RUN grunt build
# RUN npm test:build
# BUILD APP IMAGE
FROM node:8.2.1
COPY --from=builder /user/src/app/dist /user/src/app/
WORKDIR /user/src/app
RUN npm install -g mongodb-migrations --quiet
RUN npm install --only=prod --quiet
EXPOSE 5000
CMD npm start
3. Jenkins作业监视ECR中的新图像并远程触发EC2实例以拉动并重新启动docker镜像
let dockerApi = new Docker({
host: DockerIpAddress,
port: process.env.DOCKER_PORT || 2375,
version: 'v1.32' // required when Docker >= v1.13, https://docs.docker.com/engine/api/version-history/
});
dockerApi.createContainer({
Image: IMAGE_NAME,
AttachStdout: true,
AttachStderr: true,
Tty: true,
Env: [`NODE_ENV=${ENV}`],
ExposedPorts: {
"5000/tcp": {},
},
HostConfig:{
PortBindings: {
"5000/tcp": [{
"HostPort": "5000"
}],
},
},
})
问题
到目前为止 - 一切正常!我的docker容器正在ec2实例上运行 . 什么's not working is that I can' t接收任何连接 . 即使从ssh进入ec2实例, curl http://localhost:5000
也赢了't work. Accessing the ec2 instance from a browser via the public ip or public host doesn' .

检查用于创建映像的Dockerfile是否运行了一个脚本,该脚本在0.0.0.0中公开服务器而不在localhost中 .
您应该打开0.0.0.0:5000->5000而不是在localhost中运行!!
希望这可以帮助 .
