# Segment Geospatial
## todo
1. export output to mask: OK local, OK aws lambda
2. resolve model paths: OK local
3. inference:
4. from mask to json (rasterio + geopandas, check for re-projection to EPSG_4326)
5. check mandatory dependencies
6. check for alternative python interpreters
## Build instructions
Build the docker image:
```bash
# clean any old active containers
docker stop $(docker ps -a -q); docker rm $(docker ps -a -q)
# build the base docker image with the docker aws repository tag
docker build . -f dockerfiles/dockerfile-lambda-gdal-runner --tag 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-gdal-runner
# OPTIONAL: to build the lambda-gdal-runner image on a x86 machine use the build arg `RIE="https://github.com/aws/aws-lambda-runtime-interface-emulator/releases/latest/download/aws-lambda-rie"`:
docker build . -f dockerfiles/dockerfile-lambda-gdal-runner --build-arg RIE="https://github.com/aws/aws-lambda-runtime-interface-emulator/releases/latest/download/aws-lambda-rie" --tag 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-gdal-runner --progress=plain
# build the final docker image
docker build . -f dockerfiles/dockerfile-lambda-fastsam-api --tag 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-fastsam-api
```
Run the container (keep it on background) and show logs
```bash
docker tag 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-fastsam-api:latest lambda-fastsam-api;docker run -d --name lambda-fastsam-api -p 8080:8080 lambda-fastsam-api; docker logs -f lambda-fastsam-api
```
Test it with curl:
```bash
URL=http://localhost:8080/2015-03-31/functions/function/invocations
curl -X 'POST' \
${URL} \
-H 'accept: application/json' \
-d '{}'
```
## Publish the aws lambda
1. Login on aws ECR with the correct aws profile (details on [ECR page](https://eu-west-1.console.aws.amazon.com/ecr/repositories/private/686901913580/surferdtm-prediction-api?region=eu-west-1))
```
aws --profile alessandrotrinca_hotmail_aws_console_ec2_lambda ecr get-login-password --region eu-west-1 | docker login --username AWS --password-stdin 686901913580.dkr.ecr.eu-west-1.amazonaws.com
```
2. Build and tag the docker images, then push them:
```
docker push 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-gdal-runner:latest
docker push 686901913580.dkr.ecr.eu-west-1.amazonaws.com/lambda-fastsam-api:latest
```
3. It's possible to publish a new aws lambda version from cmd or from lambda page |
