我正在尝试在具有Ubuntu 18.04的Vultr服务器中使用docker-compose
。我创建了以下Dockerfile
:
FROM node:latest
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./
RUN npm install -g pm2
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
EXPOSE 80
CMD [ "pm2-runtime", "server.js", "--watch" ]
docker-compose.yml
文件是:
version: '3'
services:
nginx:
image: nginx:latest
volumes:
- ./nginx/default.conf:/etc/nginx/conf.d/default.conf
ports:
- 80:80
networks:
- backbone
web:
build: ./../services/web
volumes:
- ./../services/web:/usr/src/app
networks:
- backbone
edu_entities:
build: ./../services/edu_entities
volumes:
- ./../services/edu_entities:/usr/src/app
networks:
- backbone
networks:
backbone:
driver: bridge
我得到的输出如下:
root@vultr-host:~/app/config# docker-compose build
nginx uses an image, skipping

然后它在这里呆了很长时间,然后...
Killed
ERROR: Service 'web' failed to build: The command '/bin/sh -c npm install pm2' returned a non-zero code: 137
我尝试分别在-g
处分别添加标志--unsafe-perm
和RUN npm install pm2
。我还尝试在每个USER node
中添加Dockerfile
,但也没有用。
我的文件结构如下:

编辑:正如@codestation在评论中所说,主机VM中可能缺少可用的RAM。我今天早上尝试运行docker-compose build
,但效果很好。但是,现在出现以下错误:
root@vultr-host:~/app/config# docker-compose up
Starting config_nginx_1 ...
Starting config_web_1 ...
Starting config_nginx_1
Starting config_web_1 ... error
ERROR: for config_web_1 Cannot start service web: OCI runtime create failed: container_linux.go:348: starting contain
Starting config_nginx_1 ... done
ERROR: for web Cannot start service web: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"pm2-runtime\": executable file not found in $PATH": unknown
ERROR: Encountered errors while bringing up the project.
编辑2:事实证明,我必须在-g
中添加RUN npm install pm2
标志。然后我遇到了另一个错误,那就是容器找不到express
。我通过从本地计算机(容器外部)运行npm install
来解决它,并且卷配置设法将node_modules
文件夹同步到容器中。
答案 0 :(得分:0)
最初的错误是Vultr主机VM没有足够的可用RAM,因此docker-compose build
在必须安装pm2
时失败。然后,我还必须在服务的-g
的{{1}}中添加RUN npm install pm2
标志。我还必须在容器外部运行Dockerfile
来添加其他依赖项,并让该卷将它们放入容器中。
所有这些之后,NGINX能够提供该页面,并且现在它已启动并正在运行。 :)
