# Update to CentOS 7 Docker install one-liner > Discover the updated one-liner Docker installer for CentOS 7. Install Docker 1.7 and docker-compose effortlessly with the official RPM and a single command. - Canonical: https://www.russ.cloud/2015/06/28/update-to-centos-7-docker-install-one-liner/ - Published: 2015-06-28 - Author: Russ McKendrick - Tags: Linux, Docker --- **UPDATE 26/07/2015** In typical fashion, a few weeks after posting this Docker themselves released a much better version than mine, you can install it using the following commands; ```bash frame="terminal" title="Update to CentOS 7 Docker install one-liner 1/2" curl -sSL https://get.docker.com/ | sh systemctl enable docker && systemctl start docker docker run hello-world ``` What follows is the original, now mostly redundant post. It’s been a while since I touched the code for [the one-liner Docker installer I wrote a while back](/2014/11/02/installing-docker-1.3.x-on-centos-7/ "Installing Docker 1.3.x on CentOS 7"). Times have moved on, the official CentOS version is more up-to-date than it was once was (it’s currently at 1.6) and Docker now provide [their own RPM](https://docs.docker.com/engine/install/centos/ "Offical Docker Docs - "Linux"") for installing the latest version (currently 1.7) on CentOS 7. Also, [docker-compose](/2015/03/21/docker-machine-compose-swarm/ "Docker Machine, Compose & Swarm") has replaced [fig](/2014/08/31/docker-fig-nginx-reverse-proxies-and-centos-7/"Docker, Fig, NGINX Reverse Proxies and CentOS 7"). As I am going to be doing a lot with Docker over the next few months (more on that in the next few weeks) I decided it was time to update the script. It now downloads a copy of the official RPM from get.docker.com as well as installs the latest version of docker-compose, to help with the muscle memory it creates an alias for fig so that you can still use the command (just remember to call you configuration docker-compose.yml and not fig.yml). You can see the updated script in action below; asciicast or run it using; ```bash frame="terminal" title="Update to CentOS 7 Docker install one-liner 2/2" curl -fsS https://raw.githubusercontent.com/russmckendrick/docker-install/master/install-offical | bash ``` It is also available at [GitHub](https://github.com/russmckendrick/docker-install "docker-install").
