Colima Runtime

⚠️ This page is for macOS platform users only.

macOS users looking for a lightweight alternative to Docker Desktop can install and run Colima instead with no GUI overhead.

Colima can be installed through IGM menu. Alternatively, you can run the IGM CLI command igm runtime. You'll need to remove Docker first before installing Colima.

When installing Colima, you have the option to specify the amount of resource allocate to Colima. You can configure this later and accept the default.

The following table shows the resource allocation:

Colima Configuration	CPU	RAM	DISK
Default Setup	1	2	10
Recommended	2	4	20

Configuring Colima can be done at any time via IGM menu or via CLI igm runtime. On configuring, IGM will dynamically detect your system resource and will allow you to allocate 75% it, which is shared with the macOS host. In practice, you won't be assign all of the resource, and follow the recommended is more than sufficient.

Additionally, since Colima doesn’t start automatically at boot, two Launch Agent plist files will be added to the host system. This allows macOS to automatically start and run Colima when the system starts. They are automatically removed when Colima is removed.
