Ready to use containers

You can find fully baked containers, using the dockerfiles provided in this repository, on the public docker registry

Projects

These are the currently available projects

hashicorp-vault

Hashicorp Vault on a tiny busybox

# Run example

docker run -p 8300:8300 kintoandar/hashicorp-vault

test-kitchen

Fully provisioned CentOS x86_64 container with test-kitchen to enable easy chef cookbook testing

curl-loader

Installs curl-loader on a clean CentOS x86_64

etsy-mixer

Installs etsy mixer platform for testing

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...
Connected to example.com.
Escape character is '^]'.
SSH-2.0-OpenSSH_5.3
^C
Connection closed by foreign host.

hashicorp-consul

hashicorp consul on a tiny busybox

toolkit

Container toolkit for debugging running containers

Example

Just replace CONTAINER_HASH with the hash of the running container where you want to attach the toolkit

docker run -it \
  --pid=container:CONTAINER_HASH \
  --net=container:CONTAINER_HASH \
  --cap-add sys_admin \
  kintoandar/toolkit

Docker run reference page has useful information regarding this

Manual build example

If you want to build the container yourself, here's an easy to follow example:

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

Docker Compose

Compose is a tool for defining and running multi-container Docker applications.

These are the available Compose files, using the containers available in this repo, for fun and profit:

• Vault with Consul backend

Useful bash aliases

You can find some useful bash aliases for interacting with the docker server on my dotfiles repo
