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'
And simply invoke curl www.example.com to make a request
