At some point all your backend servers might go down. Maybe your whole infra goes down,
except for your load balancers. Incoming requests cannot be served as there are no servers
in the host pool.
While the infra recovers, or if you are in the unfortunate position of recovering things manually,
you might want to show a static web page to all frontend requests. There are many ways to achieve this:
- Have a readily available pool of hosts capable of serving static content, in a separate infra. Running hosts all the time for this purpose is just an unnecessary cost.
- Spin up new hosts or pods, which run a webserver such as Nginx. Use Terraform, Ansible, Kubernetes or $whatever to do this.
- Configure a web server manually somewhere.
In any case you still have to configure and optimize your webservers and glue them into your load balancers.
Or you can just use this repo, add a single HTML file and build yourself a container! Dockerhub images available too.
Build the container by running
docker build -t my-gorry-server .
You can compile a static binary too just by running
Run the pre-baked Docker image from Dockerhub by mounting a local HTML file to the container. Example:
$ docker run --rm -d \ -v /var/www/html/emergency.html:/go/src/app/index.html vtorhonen/gorry-server
/go/bin/app as the entrypoint. Define a custom entrypoint to swim inside.
$ docker run --rm -it --entrypoint /bin/bash vtorhonen/gorry-server
gorry-server -h to print out the help message.
