# 3.2. Development Commands, Tricks, and Hints (WORK IN PROGRESS)



## Items to be addressed:
- pytest flags: --log-level=INFO --verbose -o log_cli=true -o log_file=my_log_file.log -o log_file_level=DEBUG
- code coverage
- nginx ingress grpc to enable access from external sources


# interesting Docker commands

Build by hand:
cd src
docker build -t "context:lgr-test" -f ./context/Dockerfile .

Run by hand:
docker run --rm --name lgr-test -it --env "DB_BACKEND=inmemory" --entrypoint /bin/bash context:lgr-test


## Expose gRPC ports through Ingress Controller
source `my_deploy.sh`
run script `./expose_ingress_grpc.sh`

to test:
sudo apt-get install nmap
nmap -p 1010 127.0.0.1  # test if context is reachable
should retrieve something like:
$ nmap -p 1010 127.0.0.1
