我正在尝试将多个 docker 容器部署到 Elastic Beanstalk。有两个容器，一个用于 Supervisor+uwsgi+django 应用程序，另一个用于 JavaScript 前端。
使用 docker-compose 在本地运行良好
我的docker-compose文件：
version: '2'
services:
frontend:
image: node:latest
working_dir: "/frontend"
ports:
- "3000:3000"
volumes:
- ./frontend:/frontend
- static-content:/frontend/build
command: bash -c "yarn install && yarn build"
web:
build: web/
working_dir: "/app"
volumes:
- ./web/app:/app
- static-content:/home/docker/volatile/static
command: bash -c "pip3 install -r requirements.txt && python3 manage.py migrate && supervisord -n"
ports:
- "80:80"
- "8000:8000"
depends_on:
- db
- frontend
volumes:
static-content:
nodejs 的镜像是官方的 Docker 镜像。对于“web”，我使用以下 Dockerfile：
FROM ubuntu:16.04
# Install required packages and remove the apt packages cache when done.
RUN apt-get update && \
apt-get upgrade -y && \
apt-get install -y \
python3 \
python3-dev \
python3-setuptools \
python3-pip \
nginx \
supervisor \
sqlite3 && \
pip3 install -U pip setuptools && \
rm -rf /var/lib/apt/lists/*
# install uwsgi now because it takes a little while
RUN pip3 install uwsgi
# setup all the configfiles
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
COPY nginx-app.conf /etc/nginx/sites-available/default
COPY supervisor-app.conf /etc/supervisor/conf.d/
EXPOSE 80
EXPOSE 8000
但是，AWS 使用自己的“compose”设置，该设置定义在 dockerrun.aws.json 中，语法不同，因此我必须对其进行调整。首先，我使用了容器变换应用程序根据我的docker-compose生成文件
然后我必须做一些调整，即：AWS 文件似乎没有“workdir”属性，所以我不得不根据
我还将我的镜像发布到了 AWS Elastic Container Registry
文件变成如下形式：
{
"AWSEBDockerrunVersion": 2,
"containerDefinitions": [
{
"command": [
"bash",
"-c",
"yarn install --cwd /frontend && yarn build --cwd /frontend"
],
"essential": true,
"image": "node:latest",
"memory": 128,
"mountPoints": [
{
"containerPath": "/frontend",
"sourceVolume": "_Frontend"
},
{
"containerPath": "/frontend/build",
"sourceVolume": "Static-Content"
}
],
"name": "frontend",
"portMappings": [
{
"containerPort": 3000,
"hostPort": 3000
}
]
},
{
"command": [
"bash",
"-c",
"pip3 install -r /app/requirements.txt && supervisord -n"
],
"essential": true,
"image": "<my-ecr-image-path>",
"memory": 128,
"mountPoints": [
{
"containerPath": "/app",
"sourceVolume": "_WebApp"
},
{
"containerPath": "/home/docker/volatile/static",
"sourceVolume": "Static-Content"
},
{
"containerPath": "/var/log/supervisor",
"sourceVolume": "_SupervisorLog"
}
],
"name": "web",
"portMappings": [
{
"containerPort": 80,
"hostPort": 80
},
{
"containerPort": 8000,
"hostPort": 8000
}
],
"links": [
"frontend"
]
}
],
"family": "",
"volumes": [
{
"host": {
"sourcePath": "/var/app/current/frontend"
},
"name": "_Frontend"
},
{
"host": {
"sourcePath": "static-content"
},
"name": "Static-Content"
},
{
"host": {
"sourcePath": "/var/app/current/web/app"
},
"name": "_WebApp"
},
{
"host": {
"sourcePath": "/var/log/supervisor"
},
"name": "_SupervisorLog"
}
]
}
但部署后我在日志中看到它：
> ------------------------------------- /var/log/containers/frontend-xxxxxx-stdouterr.log
>
> ------------------------------------- yarn install v1.3.2
> [1/4] Resolving packages...

我尝试增加 yarn 的超时时间，但错误仍然发生
我甚至无法在容器上执行 bash（它会永远卡住）或任何其他命令（即：尝试重现纱线问题）
而且 _SupervisorLog 似乎没有映射，文件夹是空的，我无法准确理解发生了什么，也无法正确重现错误
如果我尝试访问该 URL，有时会收到错误网关，有时甚至不会收到错误网关。如果我尝试访问应该加载“前端”的路径，则会收到“禁止”错误。需要澄清的是，当我使用 docker-compose 在本地运行容器时，此操作运行正常。
我最近开始使用 Docker，因此请随意指出您在我的文件中发现的任何其他问题。
