Golang binary is built with static link. You can download it directly from the GitHub Release page or build it by yourself by cloning this repo and running make.
A Docker image is available for amd64, arm and arm64 platforms on Docker Hub: vibioh/goweb.
You can configure app by passing CLI args or environment variables (cf. Usage section). CLI override environment variables.
You'll find a Kubernetes exemple in the infra/ folder, using my app chart
Following variables are required for CI:
| Name | Purpose |
|---|---|
| DOCKER_USER | for publishing Docker image |
| DOCKER_PASS | for publishing Docker image |
| SCRIPTS_NO_INTERACTIVE | for running scripts in CI |
The application can be configured by passing CLI args described below or their equivalent as environment variable. CLI values take precedence over environments variables.
Be careful when using the CLI values, if someone list the processes on the system, they will appear in plain-text. Pass secrets by environment variables: it's less easily visible.
