Build and run the image locally

To build the image

cd citycat-image
DOCKER_BUILDKIT=1 docker build --tag=citycat-image:latest .

Note: Make sure you are in the correct directory when you try to build the image.

To run

Note: You need to download the CityCat.exe and Domain_DESC.asc from the buckets before running the image.

The following mounts the 3 local directories and uses the default environment variables and entry point.

docker run -it -v $(pwd)/climateiq-flood-simulation-input:/mnt/disks/share/climateiq-flood-simulation-input -v $(pwd)/climateiq-flood-simulation-output:/mnt/disks/share/climateiq-flood-simulation-output -v $(pwd)/climateiq-flood-simulation-config:/mnt/disks/share/climateiq-flood-simulation-config citycat-image:latest

CityCat is running correctly if you see something like the following:

0024:err:winediag:nodrv_CreateWindow Application tried to create a window, but no driver could be loaded.
0024:err:winediag:nodrv_CreateWindow L"Make sure that your X server is running and that $DISPLAY is set correctly."

Override env variables

Pass the command a -e flag.

docker run -it -e CITYCAT_CONFIG_FILE=2 -e RAINFALL_DATA_FILE=2 -e STUDY_AREA=manhattan -e CONFIG=config_1 -v $(pwd)/citycat-input-test:/mnt/disks/share/citycat-input-test -v $(pwd)/citycat-output-test:/mnt/disks/share/citycat-output-test -v $(pwd)/citycat-config-test:/mnt/disks/share/citycat-config-test citycat-image:latest

Enter the container

If you want to debug, it might be helpful to enter the container and override the entrypoint script by adding the flag --entrypoint.

docker run -it --entrypoint bash -v $(pwd)/climateiq-flood-simulation-input:/mnt/disks/share/climateiq-flood-simulation-input -v $(pwd)/climateiq-flood-simulation-output:/mnt/disks/share/climateiq-flood-simulation-output -v $(pwd)/climateiq-flood-simulation-config:/mnt/disks/share/climateiq-flood-simulation-config citycat-image:latest

To exit the container, type exit.

Troubleshooting

If you make any changes to the Dockerfile or execute.sh script, you need to rebuild the image to see the changes.

Verify the image was created ``` docker images citycat-image ```

Storing the container in the Artifact Registry

  1. [If it does not already exist] Create the artifact repository
  2. Build the image
  3. Tag and push the image to the artifact repository

Create the artifact repository

Authorize via gcloud cli

PROJECT_ID=climateiq-test
gcloud auth login
gcloud config set project ${PROJECT_ID}

Running the following script creates the repository: citycat-repo

chmod +x ../artifact_repository/create.sh 
../artifact_repository/create.sh
To verify repo was created ``` gcloud artifacts repositories list ```

Troubleshooting

To delete a repo (if you want to change the name or create a new one) ``` gcloud artifacts repositories delete citycat-repo --location=us-central1 ```

Alternative ways to create the repository

Alternatively, you can use the terraform to create the repository.

Build the image

Using the steps above in building the image locally

Tag and push the image to the artifact repository

Running the following script tags and pushes the image

chmod +x ../artifact_repository/submit.sh 
PROJECT_ID="climateiq-test" ../artifact_repository/submit.sh
Verify the project id is correct depending on what project you want to use

If you are getting denied: Permission "artifactregistry.repositories.uploadArtifacts" denied on resource "X", make sure the project id (PROJECT_ID) env variable is set to the correct one.

You can also try the following

gcloud config set project ${PROJECT_ID}
gcloud auth login application-default
gcloud auth configure-docker ${LOCATION}-docker.pkg.dev
