GOV.UK PaaS Admin

⚠️ When merging pull requests, please use the gds-cli or github_merge_sign ⚠️

Overview

A web UI for interacting with GOV.UK PaaS (CloudFoundry).

It aims to be a progressive enhanced, well tested and user researched tool that tenants can use to complement their use of the CLI.

Usage

npm run build              # compile the build to ./dist
npm run test               # run all the tests and linters
npm run test:unit          # only unit tests
npm run lint               # run code linters
npm run fix                # try to autofix problems with js/css
npm run start              # rebuild and start the server
npm run push               # rebuild and push to cloudfoundry
npm run clean              # destroy the ./dist build dir

Prerequisites

You will need to add a UAA client to your CloudFoundry deployment manifest, for example:

paas-admin:
  override: true
  authorized-grant-types: authorization_code,client_credentials,refresh_token
  autoapprove: true
  secret: [CF_CLIENT_SECRET]
  scope: cloud_controller.read,cloud_controller.admin_read_only,cloud_controller.global_auditor,cloud_controller.write,scim.me,openid,profile,uaa.user,cloud_controller.admincloud_controller.read,cloud_controller.admin_read_only,cloud_controller.global_auditor,cloud_controller.write,scim.me,openid,profile,uaa.user,cloud_controller.admin
  authorities: scim.userids,scim.invite,scim.read
  redirect-uri: "https://[pass-admin-domain.com]/auth/login/callback"

If you get problems with "Invalid redirect", use uaac to modify the redirect-uri:

uaac target https://uaa.my.environment
uaac token client get admin -s my-uaa-admin-client-secret
uaac client update paas-admin --redirect-uri http://localhost:3000/auth/login/callback

Requirements

• Node.js version ~ 14 LTS - consider using NVM (nvm use in this repo) for version management
• npm versions > 7.x.x

Getting Started

Clone this repository and then use npm to install the project dependencies:

npm install

Execute the unit tests to ensure everything looks good:

npm test

Executing the acceptance tests against dev environment:

export PAAS_ADMIN_BASE_URL=https://admin.${DEPLOY_ENV}.dev.cloudpipeline.digital
export CF_API_BASE_URL=https://api.${DEPLOY_ENV}.dev.cloudpipeline.digital
export ACCOUNTS_API_BASE_URL=https://accounts.${DEPLOY_ENV}.dev.cloudpipeline.digital
export ACCOUNTS_USERNAME=admin
export ACCOUNTS_PASSWORD= # get this value from credhub using `credhub get -n /concourse/main/create-cloudfoundry/paas_accounts_password`

export ADMIN_USERNAME=admin
export ADMIN_PASSWORD= # get this value from credhub using `credhub get -n /${DEPLOY_ENV}/${DEPLOY_ENV}/cf_admin_password`

npm run test:acceptance

Start the server pointing at stubbed APIs

# In one terminal tab
npm run start:stub-api

# In a second terminal tab
npm run start:with-stub-api

Start the server pointing at real APIs in development mode

Run:

gds aws paas-dev-admin -- npm run start:dev:with-cf-dev-env  $DEPLOY_ENV

and follow on-screen instructions.

You should be able to edit files in the ./src directory and the changes will automatically be updated.

Quick local start for review/troubleshooting

Provided you have logged in CF and have AWS credentials

1. Update uaa user:

DEPLOY_ENV=...
uaac target https://uaa.${DEPLOY_ENV}.dev.cloudpipeline.digital
uaac token client get admin -s $(aws s3 cp s3://gds-paas-${DEPLOY_ENV}-state/cf-vars-store.yml  - | grep uaa_admin_client_secret | cut -f2 -d " ")
uaac client update paas-admin --redirect-uri http://localhost:3000/auth/login/callback

2. Get the command to start the server:

cf target -o admin -s public
cf env paas-admin | awk '/User-Provided/ { printing=1; next} /^$/ { printing=0 ; next} printing  {gsub(": ","=\""); gsub("$", "\" \\"); print; next  } END { print "npm start"}'

3. Undo the paas-admin client change once done:

uaac client update paas-admin --redirect-uri https://admin.${DEPLOY_ENV}.dev.cloudpipeline.digital/auth/login/callback

Production builds

The NODE_ENV environment variable alters the build process to bundle all dependencies into the ./dist/ directory.

NODE_ENV=production npm run build

The ./dist folder should now be a distributable without the need for the node_modules folder and should be executable on any environment that has a supported version of Node.js, e.g., cf push.

To push the build to CloudFoundry there is a helper script that creates a production build and calls cf push:

npm run push

Alternatives

This project is fairly young and may not be a right fit for different needs yet.

You may be interested in investigating other tools, such as Stratos which may become an official tool some day.
