Use drone.io to build.
You'll need to install the Drone CLI:
https://docs.drone.io/cli/install/
Then run this simple cmd in this repo root:
$ drone exec
[build:0] + npm install
[build:1] npm WARN react-tabs@3.1.0 requires a peer of react@^16.3.0 but none is installed. You must install peer dependencies yourself.
[build:2] npm WARN start@0.0.1 No license field.
...
This should create a ./dist/ folder which can be released.
Note that you'll need to run npm install --only=prod.
And you'll need to copy the required page files from ./pages/.
Create a secrets.yml in the root:
docker_password: "00000000-0000-0000-0000-000000000000 "
Run Drone Docker image build:
drone exec --pipeline docker --secret-file secrets.yml
