This repo is a fork of https://github.com/cjimti/go-echo maintained by Kong. The main purpose of this fork is to have multi-arch images with both amd64 and arm64 support.
It adds UDP and HTTP echo services in addition to the original TCP and TLS services.
Run go-echo to start a echo server for different protocols, with ports configurable via environment variables
TCPon port1025adjustable withTCP_PORTUDPon port1026adjustable withUDP_PORTHTTPon port1027adjustable withHTTP_PORT
In order to run a TCP over TLS server, set TLS_PORT to the port to listen on, TLS_CA_CERT_FILE to path of CA certificate file, TLS_CERT_FILE and TLS_KEY_FILE to paths of certificate-key pair.
In order to run a HTTPs server, set HTTPS_PORT to the port to listen on, TLS_CERT_FILE and TLS_KEY_FILE to paths of certificate-key pair.
go-echo returns additional info in the form of the below message when specific environment variables are
explicitly set
Welcome, you are connected to node ${NODE_NAME}.
Running on Pod ${POD_NAME}.
In namespace ${POD_NAMESPACE}.
With IP address ${POD_IP}.
Service account ${SERVICE_ACCOUNT}.when a variable is omitted, line with a message is omitted too.
Check example_deploy.yaml for an example usage with Kubernetes.
To have a new image version, one needs to create a new Github release, and the new Docker image will be automatically built and pushed. The release has to be created manually, as there is no release automation in place.
