# The envs *_REGEX represent a regex fragment, check entrypoint.sh to understand how they're used (nginx ~ location, PCRE syntax). # Once enabled, it is valid for all registries, not only DockerHub. # Setting it to true enables the processing of the ENVs below. Disabled by default, to mimick 0.4/0.5 behaviour. The configuration ENVs are explained in the Dockerfile, relevant parts included below. Note: enabling manifest caching, in its default config, effectively makes some tags immutable. Together with the possibility to centrally inject authentication (since 0.3x), this is probably one of the best ways to bring relief to your distressed cluster, while at the same time saving lots of bandwidth and time. You can then fine-tune other parameters to your needs. Since version 0.6.0, this proxy can be configured with the env var ENABLE_MANIFEST_CACHE=true which providesĬonfigurable caching of the manifest requests that DockerHub throttles. Many unknowing Kubernetes clusters will hit the limit, and struggle to configure imagePullSecrets and imagePullPolicy. The main symptom is Error response from daemon: toomanyrequests: Too Many Requests.
