Docker-撰写我无法创建Postgress服务器 [英] Docker - Compose I can't create postgress server
问题描述
你好，我正在尝试创建一个postgres组成docker
pg admin 4
和node
Hello i'm trying to create a postgres compose docker pg admin 4 and node
但是我遇到了困难，我无法创建我的服务器：
but I'm having difficulties and I can't create my server:
我尝试了所有可能的名称，但我没有不知道我做错了什么：
I've tried with all possible names and I don't know what I'm wrong:
我的 docker compose：
version: "3.7"
services:
emasa-postgres:
image: postgres
environment:
POSTGRES_PASSWORD: emasa@
POSTGRES_USER: postgres
POSTGRES_DB: emasa
volumes:
- ./pgdata:/var/lib/postgresql/data
ports:
- "5432:5432"
networks:
- postgres-compose-network
web:
image: emasa-web
depends_on:
- emasa-postgres
ports:
- "4000:4000"
networks:
- postgres-compose-network
teste-pgadmin-compose:
image: dpage/pgadmin4
environment:
PGADMIN_DEFAULT_EMAIL: "emasa@hotmail.com"
PGADMIN_DEFAULT_PASSWORD: "emasa"
ports:
- "16543:80"
depends_on:
- emasa-postgres
networks:
- postgres-compose-network
networks:
postgres-compose-network:
driver: bridge
DockerFile ：
FROM node as builder
WORKDIR usr/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM node
WORKDIR usr/app
COPY package*.json ./
RUN npm install --production
COPY --from=builder /usr/app/dist ./dist
COPY ormconfig.docker.json ./ormconfig.json
COPY .env .
expose 4000
CMD node dist/src/index.js
我的orm config：
my orm config:
{
"type": "postgres",
"host": "db",
"port": 5432,
"username": "postgres",
"password": "emasa@",
"database": "postgres",
"synchronize": true,

"subscribers": ["src/subscriber/**/*.ts"],
"cli": {
"entitiesDir": "src/entity",
"migrationsDir": "src/migration",
"subscribersDir": "src/subscriber"
}
}
我的docker-compose记录器：
my docker-compose loggers:

我的容器ls：
docker container ls

我确实尝试使用容器名称：
I've really tried with the container names:
emasa-postgres_1
emasa-postgres
emasa-postgres_1 emasa-postgres
，但无济于事
推荐答案
可以在您提供的日志中看到问题的原因。
The cause of the problem can be seen in the log that you provided.
2020-03-17 23：48：08.890 UTC [81 ]致命：数据目录 / var / lib / postgresql / data拥有错误的所有权
2020-03-17 23:48:08.890 UTC [81] FATAL: data directory "/var/lib/postgresql/data" has wrong ownership
您可能正在Windows上运行docker机？如果是这样，这似乎是一个常见的错误-在此处检查。因此，您可能想使用永久性的docker卷，而不是la
You are probably running the docker on a Windows machine? If so, it seems to be a common bug - check here. So, you might want to use a persistent docker volume instead, a la
services:
emasa-postgres:
...
volumes:
- pgdata:/var/lib/postgresql/data
networks:
- postgres-compose-network
volumes:
pgdata:
我仍然对在pgadmin中使用哪个本地主机感到怀疑
I still have doubts about my compose which localhost to use in pgadmin
为了连接到您的来自，您可以为 pgadmin 的emasa-postgres emasa-postgres 这样的容器：
In order to connect to your emasa-postgres from pgadmin, you can set the hostname and network alias for the emasa-postgres container like so:
services:
emasa-postgres:
hostname: my_super_cool_postgres
image: postgres
networks:
postgres-compose-network:
aliases:
- my_super_cool_postgres
而不是使用 localhost 或 db 之后，您应该能够通过主机 my_super_cool_postgres 连接到数据库。
Instead of using localhost or db you should then be able to connect to the database via the host my_super_cool_postgres.
这样，您应该可以从pgadmin连接到postgres容器。如果仍然无法使用，您还可以尝试使用链接相反，这是Docker的一项传统功能，但应该可以正常工作，例如
This way, you should be able to connect to your postgres container from pgadmin. If it still doesn't work for you, you can also try using the links instead, which is a legacy feature of Docker, but should work, e.g.
services:
teste-pgadmin-compose:
image: dpage/pgadmin4
links:
- "emasa-postgres:my_super_cool_postgres"
这一次，您必须将其设置为 teste-pgadmin-compose （或从任何需要的位置）访问 emasa-postgres 容器）。然后应该可以访问主机 my_super_cool_postgres 和端口 5432 。
This time, you have to set it for the teste-pgadmin-compose (or from wherever you need to access to the emasa-postgres container). The host my_super_cool_postgres and port 5432 should then be accessible.
