Optional: Secure the GraphQL API

Protect the GraphQL API that you created in the previous sections by using an API key. Note that you can also use any other authorization mechanism provided by Gloo Edge to secure your GraphQL endpoint.

  1. Create an API key secret that contains an existing API key. If you want glooctl to create an API key for you, you can specify the --apikey-generate flag instead of the --apikey flag.

    glooctl create secret apikey my-apikey \
--apikey $API_KEY \
--apikey-labels team=gloo

  2. Verify that the secret was successfully created and contains an API key. If you had Gloo Edge generate the API key, set the value as an environment variable, export API_KEY=<api-key-value>.

    kubectl get secret my-apikey -n gloo-system -o yaml

  3. Create an AuthConfig CR that uses the API key secret.

    kubectl apply -f - <<EOF
apiVersion: enterprise.gloo.solo.io/v1
kind: AuthConfig
metadata:
  name: apikey-auth
  namespace: gloo-system
spec:
  configs:
  - apiKeyAuth:
      headerName: api-key
      labelSelector:
        team: gloo
EOF

  4. Update the default virtual service that you previously created to reference the apikey-auth AuthConfig. 

    cat << EOF | kubectl apply -f -
apiVersion: gateway.solo.io/v1
kind: VirtualService
metadata:
  name: 'default'
  namespace: 'gloo-system'
spec:
  virtualHost:
    domains:
    - '*'
    routes:
    - graphqlApiRef:
        name: bookinfo-graphql
        namespace: gloo-system
      matchers:
      - prefix: /graphql
      options:
        extauth:
          configRef:
            name: apikey-auth
            namespace: gloo-system
EOF

  5. Send a request to the GraphQL endpoint. Note that because you enforced API key authorization, the unauthorized request fails, and you get a 401 Unauthorized response.

    curl "$(glooctl proxy url)/graphql" -H 'Content-Type: application/json' -d '{"query": "query {productsForHome {id, title, author, pages, year}}"}' -v

  6. Add the API key to your request in the -H 'api-key: $API_KEY' header, and curl the endpoint again.

    curl "$(glooctl proxy url)/graphql" -H 'Content-Type: application/json' -H 'api-key: $API_KEY' -d '{"query": "query {productsForHome {id, title, author, pages, year}}"}'

    Example successful response:

    {"data":{"productsForHome":[{"id":"0","title":"The Comedy of Errors","author":"William Shakespeare","pages":200,"year":1595}]}}
