docker-compose-wait work fine but dont start container

[sptGabriel]

Hello I am having difficulty using the docker-compose-wait for my project

I have this docker file:

#building code
FROM node:lts-alpine

ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.7.3/wait /wait
RUN chmod +x /wait

RUN mkdir -p /home/node/api && chown -R node:node /home/node/api

WORKDIR /home/node/api

COPY ormconfig.json .env package.json yarn.* ./

USER node

RUN yarn

COPY --chown=node:node . .
EXPOSE 4000

CMD ["/wait", "yarn", "dev" ]

and this docker compose:

version: '3.7'
services:
  db-pg:
    image: postgres:12
    container_name: db-pg
    ports:
      - '${DB_PORT}:5432'
    environment:
      ALLOW_EMPTY_PASSWORD: 'no'
      POSTGRES_USER: ${DB_USER}
      POSTGRES_PASSWORD: ${DB_PASS}
      POSTGRES_DB: ${DB_NAME}
    volumes:
      - ci-postgres-data:/data

  ci-api:
    build: .
    container_name: ci-api
    volumes:
      - .:/home/node/api
    ports:
      - '${SERVER_PORT}:${SERVER_PORT}'
    depends_on:
      - db-pg
    environment:
      WAIT_HOSTS: db-pg:5432
    logging:
      driver: 'json-file'
      options:
        max-size: '10m'
        max-file: '5'

volumes:
  ci-postgres-data:

i got this:

ci-api    | --------------------------------------------------------
ci-api    |  docker-compose-wait 2.7.3
ci-api    | ---------------------------

but my project in node js is not starting

Hi @sptGabriel

As I read the CMD part of the Dockerfile you are providing arguments to wait. This will not work with the current implementation.

You should write something along the lines of:

CMD /wait && yarn dev

Do note the above is untested.

Please see the example in the documentation using: CMD, which demonstrates the shell form and see the Docker documentation.

CMD / wait && yarn dev

i use
CMD / wait && yarn dev
and get : ci-api | /bin/sh: /: Permission denied

if use:

CMD ["/wait", "yarn", "dev" ]

ci-api    | --------------------------------------------------------
ci-api    | Checking availability of db-pg:5432
ci-api    | Host db-pg:5432 is now available!
ci-api    | --------------------------------------------------------
ci-api    | docker-compose-wait - Everything's fine, the application can now start!
ci-api    | --------------------------------------------------------

Hi @sptGabriel

I need to come up with an example to replicate your situation. I wonder why you get a permission denied.

[ufoscout]

i use
CMD / wait && yarn dev
and get : ci-api | /bin/sh: /: Permission denied

Hi @sptGabriel,
you put a white space between "/" and "wait" so the engine is trying to execute the "/" as if it is a command. You shoud use instead: CMD /wait && yarn dev

@ufoscout thank u

Nicely spotted @ufoscout I don't know what I did not see that.
