Gitea Webhook Modifier (GWM)

This is an application that helps to modify Gitea webhook request before it reaches a GitOps system (e.g. ArgoCD or FluxCD). It replaces certain string pattern specified by a regular expression with another string anywhere in the JSON payload. By default, this is used to replace the ingress URL (e.g. http://git.localhost/) with in-cluster service URL (e.g. http://gitea-http.gitea:3000/).

Local testing and development

Run the server:

GWM_LOG_LEVEL=trace GWM_FORWARD='http://localhost:8080' go run ./cmd/gwm/main.go

Send data:

curl -v -d '{"url":"http://git.localhost/myorg/tenant1"}' localhost:8080/webhook

Usage

Install the GWM onto the cluster:

helm install -n gwm gwm oci://ghcr.io/jtyr/helm/gwm

Go to your local Gitea Web UI and define a GOGS webhook to be sent to http://gwm.gwm/webhook.

Configuration

There is several environment variables that can change the default behavior of the application:

GWM_HOST - Host name on which the HTTP server runs. Defaults to 0.0.0.0.
GWM_PORT - Port number on which the HTTP server runs. Defaults to 8080.
GWM_SEARCH - Regexp to search for a specific string to be replaced. Defaults to ^http://git.localhost/.
GWM_REPLACE - Regexp used to replace the found string. Defaults to http://gitea-http.gitea:3000/.
GWM_FORWARD - URL to which to forward the modified request. Defaults to http://argocd-server.argocd/api/webhook.
GWM_LOG_LEVEL - Log level. Possible values are panic, fatal, error, warn, info, debug and trace. Defaults to info.
