This image simply provides the curl utility inside a Docker image, based on Alpine Linux. It's for when you want to run an arbitrary curl command in a pod/container, and suddenly realise your image doesn't have curl installed.
On a Docker host:
$ docker container run --rm -it nbrown/curl https://httpbin.org/ip
{
"origin": "142.156.82.165"
}
On a Kubernetes cluster:
$ kubectl run -it --rm curl --restart=Never --image=nbrown/curl -- https://httpbin.org/ip
{
"origin": "142.156.82.165"
}
docker pull nbrown/curl
