无法运行映像，CMD [“npm”, “start”] 命令错误

Question

I just build app: docker build. -t ang:l

after try run it: docker run -d -p 83:80 ang:l

and get error:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"npm\": executable file not found in $PATH": unknown.

without this CMD ["npm", "start"] command all works, but I need server and bd.

Dockerfile:

 # Stage 0, based on Node.js FROM node:latest as node WORKDIR /app COPY package*.json./ COPY. . #RUN npm install ARG configuration=production RUN true && \ npm run build:client-and-server-bundles -- --configuration=$configuration \ && \ npm prune --production && \ true # Stage 1, based on Nginx FROM nginx:alpine COPY --from=node /app/dist /usr/src/app/ CMD ["npm", "start"]

package.json command: "start": "node dist/server",

Also I tried use docker-compose.yml:

 version: '3.4' services: app: container_name: ang image: ang:l build: context: . dockerfile: Dockerfile command: npm start ports: - '3000:3000' links: - mysql mysql: container_name: mysql image: mysql ports: - '3306:3306'

it's both variants don't work, help please, how to build it in docker

Answer 1

The nginx docker image doesn't contain npm . You'll need to use node:latest which contains npm .

# Stage 1, based on Nginx
FROM node:latest
COPY --from=node /app/dist /usr/src/app/
CMD ["npm", "start"]

You could potentially use node:alpine to run the application.
