We provide dev tooling in order to quickly get a fully configured Clair and Quay environment stood up locally. This environment can be used to test and develop Clair.
Make is used to stand up the the local dev environment. Make is readily available in just about every package manager you can think of. It's very likely your workstation already has make on it.
Currently our local dev tooling is supported by docker and docker-compose. We are making strides to provide a podman native local dev environment but we are not quite there yet.
Docker version 19.03.11 and docker-compose version 1.25.4 are confirmed working. Our assumption is most recent versions will not have an issue running the local dev tooling.

Go v1.13 or higher is required.

git clone email@example.com:quay/clair.git cd clair make local-dev-up-with-quay
After the local development environment successfully starts, the following infrastructure is available to you:
localhost:8080 --- Quay (single node, local storage) localhost:6060 --- Traefik which hosts all ClairV4 endpoints. ClairV4 services are only accessible via this load balancer. localhost:5432 --- ClairV4's Postgres DB Login: username: clair database: clair localhost:5433 --- Quay's Postgres DB Login: username: quay database: quay localhost:8081 --- Postgres GUI (pgadmin4) Login: username: firstname.lastname@example.org password: clair localhost:8082 --- OpenAPI Swagger Editor. You can view ClairV4's public API here. localhost:8087 --- RabbitMQ management GUI Login: username: guest password: guest localhost:8161 --- ActiveMQ management GUI Login: username: admin password: admin localhost:7000 --- Traefik Web UI. Good for troubleshooting http issues. localhost:9090 --- Prometheus localhost:3000 --- Grafana Login: username: admin password: admin
As mentioned above, Quay is present at
localhost:8080. You may navigate to this address and create a account. Creating an account named
admin will ensure you are a super user. An email is required, but is not validated.
Once inside, you will create an organization named "clairv4-org". Currently Quay has to explicitly enable Clair v4 security scanning, which is done via an organization allowlist. "clairv4-org" is preconfigured in our local dev configuration.
The easiest way to push to Quay is using podman:
podman pull ubuntu:latest podman login --tls-verify=false localhost:8080 # use account created in above steps podman tag ubuntu:latest localhost:8080/clairv4-org/testing:latest podman push --tls-verify=false localhost:8080/clairv4-org/testing:latest
Using docker to push is possible, however you will need to add "localhost:8080" as an insecure repository. See Insecure Repository
By default, Quay displays security scanner results on the Tags page of the given repository.
You may want to play with either Clair or Quay's configuration.
If so, the configuration files can be found inside the repository at
. Any changes to the configs will require a restart of the relevant service. Take a look at the Makefile` for the various restart targets.
will rip the entire environment down.
The most common issue encountered when standing up the dev environment is port conflicts. Make sure that you do not have any other processes listening on any of the ports outlined above.
The second issue you may face is your Docker resource settings maybe too constrained to support the local dev stack. This is typically seen on Docker4Mac since a VM is used with a specific set of resources configured. See Docker For Mac Manual for instructions on how to change these resources.
Lastly, you can view traefik's ui at
localhost:7000. If traefik is reporting no routers or services its likely SELinux has blocked its access to
/var/run/docker.socket. Place SELinuse in permissive mode and restart the local development environment.
