Cross-compile server on host, run it in container

These are simple steps using a single container.

build server on host
```
GOOS=linux GOARCH=arm64 go build
```
build docker image
```
docker build -t server-image .
```

Start container with shared directory

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

Run server in container

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

Using docker-compose

Steps to build and run the server in a multi-container environment set up by docker-compose.

Build server on host

cd ~/work-gh/mrva/mrvacommander/cmd/server/
GOOS=linux GOARCH=arm64 go build

Start the containers

cd ~/work-gh/mrva/mrvacommander/
docker-compose up -d

Run server in its container

cd ~/work-gh/mrva/mrvacommander/
docker exec -it server bash
cd /mrva/mrvacommander/cmd/server/ 
./server -loglevel=debug -mode=container

Test server via remote client by following the steps in gh-mrva

Some general docker-compose commands

Get service status
```
docker-compose ps
```
Stop services
```
docker-compose down
```
View all logs
```
docker-compose logs
```

check containers from server container

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

Some postgres specific commands

Access PostgreSQL

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

List all tables
```
\dt
```

To run pgmin, the minimal go/postgres test part of this repository:

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

Check table contents

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