Container

Both docker and podman are containerization tools. The docker image is hosted at https://hub.docker.com/r/curlimages/curl

You can run the latest version of curl with the following command:

Command for docker:

docker run -it --rm docker.io/curlimages/curl www.example.com

Command for podman:

podman run -it --rm docker.io/curlimages/curl www.example.com

Running curl seamlessly in container

It is possible to make an alias to seamlessly run curl inside a container as if it is a native application installed on the host OS.

Command to define curl as an alias for your containerization tool in the Bash, ZSH, Fish shell:

Bash or zsh

Invoke curl with docker:

alias curl='docker run -it --rm docker.io/curlimages/curl'

Invoke curl with podman:

alias curl='podman run -it --rm docker.io/curlimages/curl'

Fish

Invoke curl with docker:

alias -s curl='docker run -it --rm docker.io/curlimages/curl'

Invoke curl with podman:

alias -s curl='podman run -it --rm docker.io/curlimages/curl'

Simply invoke curl www.example.com to make a request

Running curl in kubernetes

Sometimes it can be useful to troubleshoot k8s networking with curl, just like :

kubectl run -i --tty curl --image=curlimages/curl --restart=Never \
  -- "-m 5" www.example.com
