![]() ![]() Then we need to launch an update-grub and reboot the server. We do this by changing the /etc/default/grub file and the GRUB_DEFAULT to 1. We then need to ask the server to boot on this new kernel. More information on which kernel to use for your version of Ubuntu. To do this, we need to log in to the VPS and use the following command to allow us to download and install the latest generic kernel for Ubuntu: We need to install a compatible kernel as the kernel automatically provided by OVH doesn't allow Docker to install or work properly. Websites are contained in separate containers, which you can easily move and upgrade without having to reconfigure the application environment every time.īefore you can install Docker on a VPS Cloud, you need to modify the VPS kernel. Lastly, Docker makes it easier to administer and maintain servers that host a large number of websites. ![]() In real terms, if the website gets overloaded tomorrow, we can easily move the database container to a second VPS or a physical dedicated server. announced that it had signed an agreement with Microsoft to make the solution available on Windows operating systems ( more info here ). As Docker containers are independent from the platform they run on, we can easily move them to another server on Linux. This won't impact our other containers.Īnother great thing: the solution's scalability. If one of the containers is pirated, we simply have to stop it, restore a backup of it, apply the updates and patches straightaway and then relaunch the it. By doing this, we can access WordPress configuration files in the event of an issue with WordPress, but never the VPS itself or the Piwik application. The first great thing for us in using Docker is the isolation it provides by installing the different components within separate containers to increase the security of our server. ![]()
