Docker-gitlab: docker registry log warns about redis

[rakesh-k]

Here is the log from the docker registry that I tried to run through a docker-compose.yml. Not sure if the registry needs to point to a redis instance or not?

time="2016-09-01T02:16:37.36649972Z" level=warning msg="No HTTP secret provided - generated random secret. This may cause problems with uploads if multiple registries are behind a load-balancer. To provide a shared secret, fill in http.secret in the configuration file or set the REGISTRY_HTTP_SECRET environment variable." go.version=go1.6.2 instance.id=da01c358-8b1c-49fc-bc5d-3dc865e7bf66 service=registry version=v2.4.1 time="2016-09-01T02:16:37.366768666Z" level=info msg="redis not configured" go.version=go1.6.2 instance.id=da01c358-8b1c-49fc-bc5d-3dc865e7bf66 service=registry version=v2.4.1 time="2016-09-01T02:16:37.36673635Z" level=info msg="Starting upload purge in 46m0s" go.version=go1.6.2 instance.id=da01c358-8b1c-49fc-bc5d-3dc865e7bf66 service=registry version=v2.4.1 time="2016-09-01T02:16:37.393826839Z" level=info msg="using inmemory blob descriptor cache" go.version=go1.6.2 instance.id=da01c358-8b1c-49fc-bc5d-3dc865e7bf66 service=registry version=v2.4.1 time="2016-09-01T02:16:37.395046322Z" level=info msg="listening on [::]:5000" go.version=go1.6.2 instance.id=da01c358-8b1c-49fc-bc5d-3dc865e7bf66 service=registry version=v2.4.1

Here is the portion of the docker-compose for registry:

registry:
    restart: always
    image: registry:2.4.1
    volumes:
    - /sdata/srv/docker/gitlab/gitlab/shared/registry:/registry
    - /sdata/srv/docker/gitlab/certs:/certs
    environment:
    - REGISTRY_LOG_LEVEL=info
    - REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/registry
    - REGISTRY_AUTH_TOKEN_REALM=http://cd3labvdapp001:10080/jwt/auth
    - REGISTRY_AUTH_TOKEN_SERVICE=container_registry
    - REGISTRY_AUTH_TOKEN_ISSUER=gitlab-issuer
    - REGISTRY_AUTH_TOKEN_ROOTCERTBUNDLE=/certs/registry-auth.crt
    - REGISTRY_STORAGE_DELETE_ENABLED=true

Hey,
i use the docker registry without redis and I see no problems. It depends on what you need. If you need a good cache use redis. If you not using redis a local file cache will be used default by the registry.

Use

      - REGISTRY_HTTP_SECRET=secretstring

for http secret warning and

      - REGISTRY_STORAGE_CACHE_BLOBDESCRIPTOR=redis
      - REGISTRY_REDIS_ADDR=redis:6379

for redis
