The KrakenD team is pleased to announce the release of KrakenD 2.1. You can get it packaged from the download page.

KrakenD 2.1 brings a new ready-to-use Kibana dashboard, an updated Grafana Dashboard for InfluxDB v2 and more features and bugfixes described below:

New features:

• Added a krakend version command that outputs the KrakenD, Go, and Glibc versions.
• Added allow_insecure_connections flag to ease development stages that use self-signed certificates.
• Easier logging to disk or remote server logging via the configurable syslog facility
• Customizable response body for 404 and 405 errors
• Added context propagation between Handler plugins and KrakenD Client plugins (router gin 1.8.1)
• Added capacity and client_capacity (token bucket size) to router rate limit, previously only on backend rate limit.
• We have created a new git repository Telemetry Dashboards that includes:
• A new Kibana dashboard

• A Grafana dashboard for Influx v2, using Flux queries and its datasource files.
• Logstash ingestion configurations
• Influx v2 automatic Auth creation

Relevant fixes:

• Logging consistency (Bot detector, Bloom filter, Gologging)
• Better control of errors when GELF is failing
• Influx client not initialized during startup randomly (namespace collision being the cause)
• The check-plugin command could panic when analyzing malformed files.
