Question

你好，我正在尝试运行一个脚本，以便在连接postgres后立即启动我的yarn开发：

until psql -c '\l'; do
  echo >&2 "$(date +%Y%m%dt%H%M%S) Postgres is unavailable - sleeping"
  sleep 1
done
echo >&2 "$(date +%Y%m%dt%H%M%S) Postgres is up - executing command"

exec ${@}

docker文件：

    #building code
    FROM node:lts-alpine

    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 . .

    RUN apk add --no-cache openssl

    COPY wait-pg.sh ./
    RUN chmod +x /wait-pg.sh
    ENTRYPOINT ["/wait-pg.sh"]

    EXPOSE 4000

    CMD ["yarn", "dev"]

泊坞窗撰写：

    container_name: db-pg
    ports:

并收到此错误：

您收到此错误，因为您要使用的节点用户没有运行该命令的权限。将用户定义移至命令之后，如下所示：

  #building code
    FROM node:lts-alpine

    RUN mkdir -p /home/node/api && chown -R node:node /home/node/api
    WORKDIR /home/node/api
    COPY ormconfig.json .env package.json yarn.* ./

    RUN yarn
    COPY --chown=node:node . .
    RUN apk add --no-cache openssl
    COPY wait-pg.sh .
    RUN chmod +x ./wait-pg.sh

    USER node



    ENTRYPOINT ["./wait-pg.sh"]
    EXPOSE 4000
    CMD ["yarn", "dev"]

Docker：运行脚本：错误：无法锁定数据库：权限被拒绝
