Red Hat UBI9 Wasp Deployment

0-README.md

Building Wasp for Red Hat's UBI9 image can be done with a custom Docker file and with a few simple steps that we encoded in the build.sh script.

Just put both the build.sh script and the Dockerfile at the root of your Wasp project. Make sure to make the build.sh executable with chmod +x build.sh.

There is also a test.sh script that builds the Docker image and runs it (to make sure it works)

build.sh

set -e

server_url="http://localhost:8080"

# Build the app
wasp build

# Build the web-app
cd .wasp/build/web-app && REACT_APP_API_URL=$server_url npm run build && cd -

# Override the Dockerfile with the one in .wasp/build
cp Dockerfile .wasp/build
