⁠Projects

These are the currently available projects

⁠CentOS x86_64

This container was built from scratch to have the smallest size footprint and it's currently being used by some of my dockerfiles

You may have a look in my kickstart files⁠

⁠fwd

fwd⁠ is a network port forwarder written in golang

If you ever need to connect to a non-privileged port when you have a firewall in between allowing only 80/443, this container might help

⁠ENV variables

• SRC_PORT: Exposed port on the container
• TO: destination address (host:port)

⁠Example

Launch the container bound to port 80 on my.container.com redirecting the connection to port 2222 on example.com

docker run -d -e SRC_PORT="80" -e TO="example.com:2222" -p 80:80 kintoandar/fwd

Connect on port 80 on my.container.com and end up in example.com port 2222

telnet my.container.com 80
Trying 127.201.15.89...

⁠Manual build example

git clone https://github.com/kintoandar/dockerfiles.git
cd dockerfiles/curl-loader
docker build .
