Reporting an issue

If you believe you have discovered a defect in Gatekeeper please open an issue in our Issue Tracker. Please remember to provide a good summary, description as well as steps to reproduce the issue.

Getting started

To run Gatekeeper, you can build it using this command:

docker buildx build --platform linux/amd64,linux/arm64 -t quay.io/gogatekeeper/gatekeeper:2.13.0 .

or you can use aleady existing Docker image by running:

docker run -it --rm quay.io/gogatekeeper/gatekeeper:2.13.0 \
      --listen 127.0.0.1:8080 \
      --upstream-url http://127.0.0.1:80 \
      --discovery-url https://keycloak.example.com/realms/<REALM_NAME> \
      --client-id <CLIENT_ID>

For more details refer to the Documentation.

Verifying Download

Beside links to archives of binaries we provide also checksum file containing checksums for archives. You can download file gatekeeper-checksum.txt, it contains sha512 checksums e.g.:

324b34ece86b6214f835ba9fd79e185864a9005f514458796c22c053de63f428235d2d2a04864065a49c090ad81d2daeb45546544fdd9531a8dea1a43145b8f0  gatekeeper_2.13.0_windows_amd64.zip

f5322e41b3d78017191246bdd54f99e9b3dd8d5ff9d224e7e81b678a952c1d5aae125ea4c251928969b0a0ea0dc59724308c918993c8227f384f61896f58cbd0  gatekeeper_2.13.0_macOS_amd64.tar.gz

After you download archive of binary you can calculate it's checksum by using e.g. sha512sum Linux utility:

sha512sum /my/path/gatekeeper_2.13.0_linux_amd64.tar.gz
38759e75a94d130758cd26958bd9a66b261be8d58a6c7a0fc04845157649aaf628d22a115c95285b405f8e4d6afa8bd78ca8677d1304faf06db93a0cbbc831a6  gatekeeper_2.13.0_linux_amd64.tar.g

As you can see output of command is checksum, you can compare it with the one in gatekeeper-checksum.txt.

Additionally to verify gatekeeper-checksum.txt is valid we provide also signature of checksum file gatekeeper-checksum.txt.sig.

You can validate signature with these steps:

1. Download and save gpg public key:
