#Docker mac os set up software
As installing software by a certain vendor with a red logo will take a lot of space, we’ll have to modify a parameter in Docker to get it set up right.Įdit the file /etc/sysconfig/docker, and set the OPTIONS entry to have -storage-opt dm.basesize=20G. The default Docker installation only accommodates for images with a maximum size of 10GB.
#Docker mac os set up install
Switch to the root user ( su -) and install Docker with the following command: host# yum install dockerĪfter successful completion of this command, we have installed Docker! Modify installation for big images You might run into some unexpected issues when SELinux is not disabled! Install software SElinux must be set to Disabled or Permissive in /etc/sysconfig/selinux to use the (default) btrfs storage engine on Oracle Linux 7. Enable addons repository on Oracle Public YumĮdit /etc//public-yum-ol7.repo and set enabled=1 in the stanza. For Oracle Linux users without an active support subscription: Docker is available in the ol7_addons repository on Oracle Public Yum.Īs we don’t have an active subscription, we need to use the public repository. In this series, we’ll display prompts as follows: host# - a command you type on the host system (as root)Ĭontainer# - a command you type inside the container (as root)Ĭontainer$ - a command you type inside the container (as oracle) Installing Dockerįor Oracle Linux customers with an active support subscription: Docker is available in the ol7_x86_64_addons channel for Oracle Linux 7 on the Unbreakable Linux Network (ULN). You’ll need at least 40GB of free space and 8GB of RAM. Make sure your OS has sufficient space on its hard disk, and also enough RAM. Our machine has an Intel i7 processor from the Sandy Bridge range, 16GB RAM and 500GB HDD. We are running a VirtualBox virtual machine with OEL7.1 Server on a Windows 7 machine, which works just as well. In the next steps we will get it ready for our Docker images. Through clever use of Oracle Virtualbox and a very minimal customised Tiny Core Linux installation in the tool Boot2Docker, the software also is available for Windows (7+) and Mac (OS X 10.6+)ĭocker has very comprehensible documentation about installing Docker on a variety of platforms, but here we will run you through the installation on Oracle Enterprise Linux 7.1 (OEL7.1)įor the remainder of this series we will use OEL7.1 as the host OS.
As Docker relies on Linux specific virtualization features like cgroups and namespaces, the tool is only available for Linux.
