cross-compile server on host, run it in container

1. build server on host

   GOOS=linux GOARCH=arm64 go build
   

2. build docker image

   docker build -t server-image .
   

3. Start container with shared directory

   docker run -it \
          -v   /Users/hohn/work-gh/mrva/mrvacommander:/mrva/mrvacommander \
          server-image
   

4. Run server in container

   cd /mrva/mrvacommander/cmd/server/ && ./server
   

Using docker

1. start the services

   docker-compose up -d
   

2. get status

   docker-compose ps
   

3. stop services

   docker-compose down
   

4. view all logs

   docker-compose logs
   

5. check containers from server container

   docker exec -it server bash
   curl -I postgres:5432
   curl -I http://rabbitmq:15672
   

6. Accessing PostgreSQL

   psql -h localhost -p 5432 -U exampleuser -d exampledb
   

7. List all tables

   \dt
   

8. Run pgmin

   cd ~/work-gh/mrva/mrvacommander/cmd/postgres
   GOOS=linux GOARCH=arm64 go build
   docker exec -it server bash
   /mrva/mrvacommander/cmd/postgres/postgres
   

   Exit the container. Back on the host:

   psql -h localhost -p 5432 -U exampleuser -d exampledb
   \dt
   

   Should show

           List of relations
    Schema |    Name     | Type  |    Owner
   --------+-------------+-------+-------------
    public | owner_repos | table | exampleuser    
   

9. Check table contents

   exampledb=# select * from owner_repos;
    owner |  repo
   -------+---------
    foo   | foo/bar
