Cross-compile server on host, run it in container

These are simple steps using a single container.

1. build server on host

   GOOS=linux GOARCH=arm64 go build
   

2. build docker image

   cd cmd/server
   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-compose

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

1. Built the server-image, above

2. Build server on host

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

3. Start the containers

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

4. 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
   

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

Some general docker-compose commands

2. Get service 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 http://rabbitmq:15672
   

Use the minio ql database db

1. Web access via

   open http://localhost:9001/login
   

   username / password are in docker-compose.yml for now. The ql db listing will be at

   http://localhost:9001/browser/qldb
   

2. Populate the database by running

   ./populate-dbstore.sh
   

   from the host.

3. The names in the bucket use the owner_repo format for now, e.g. google_flatbuffers_db.zip. TODO This will be enhanced to include other data later

4. Test Go's access to the dbstore -- from the host -- via

   cd ./test
   go test -v
   

   This should produce

   === RUN   TestDBListing
   dbstore_test.go:44: Object Key: google_flatbuffers_db.zip
   dbstore_test.go:44: Object Key: psycopg_psycopg2_db.zip
   

Use the minio query pack db

1. Web access via

   open http://localhost:19001/login
   

   username / password are in docker-compose.yml for now. The ql db listing will be at

   http://localhost:19001/browser/qpstore
   

To run Use the minio query pack db
