network-driver string network driver to use (slirp, gvproxy) (default "gvproxy") network-address assign reachable IP address to the VM ![]() mount-type string volume driver for the mount (sshfs, 9p) (default "sshfs") V, -mount strings directories to mount, suffix ':w' for writable m, -memory int memory in GiB (default 2) kubernetes-version string must match a k3s version (default "v1.25.0+k3s1") kubernetes-ingress enable Traefik ingress controller env stringToString environment variables for the VM (default ) vim, nano, code (default "$EDITOR" env var) editor string editor to use for edit e.g. e, -edit edit the configuration file before starting n, -dns ipSlice DNS servers for the VM (default ) d, -disk int disk size in GiB (default 60) cpu-type string the CPU type, options can be checked with 'qemu-system-aarch64 -cpu help' a, -arch string architecture (aarch64, x86_64) (default "aarch64") activate set as active Docker/Kubernetes context on startup (default true) Run 'colima template' to set the default configurations or 'colima start -edit' to customize before startup.Ĭolima start -runtime containerd -kubernetesĬolima start -cpu 4 -memory 8 -disk 100 Start Colima with the specified container runtime and optional kubernetes.Ĭolima can also be configured with a YAML file. To get the full list of available options, run colima start -h. You can easily customize your instance by using flags.Īs an example, colima start -c 5 -m 4 -d 100 will start a 4 GB memory with 5 CPUs, an 100 GB disk and a Docker runtime instance. The default colima start will set up an instance with 2 GB memory, 2 CPUs, 60 GB disk and a Docker runtime. Note: A future post will cover Kubernetes management with Colima. ![]() Last but not the least, kubectl is required to use Kubernetes by running brew install kubectl. selecting a Kubernetes version with the -kubernetes-version flag.deploying an ingress controller Traefik with the -kubernetes-ingress flag.picking a specific runtime with the -r flag.They are other options available with the Kubernetes cluster: KubernetesĬolima includes a standalone K3s server, so you can manage a Kubernetes cluster using colima start -k. NOTE: containerd is not covered in this article. brew install docker docker-compose containerdĬontainerd is available by running colima start -r containerd. Dockerĭocker is Colima's default runtime, meaning features from Docker are available out of the box.ĭocker and docker-compose CLIs are required to use Docker with Colima. ![]() Two container runtimes are supported by Colima: Docker (default) and containerd. Note: Other installation options are available here.įor a smoother experience, add Colima autocompletion to your terminal.įinally, run colima start to start a default instance. Using Homebrew as package manager, run brew install colima to install it. Please find the testing scripts on Github. Time to get our hands dirty! Let's run some scripts to compare Colima and Docker Desktop performance.įor the purpose of the tests, we gonna compare I/O using volumes and (^) calculation inside the container.īoth VMs have the same configuration (2Gb memory, 2 CPUs, 60Gb disk).įiles management and CPU stress load will be triggered using the official alpine Docker image. What is Colima?Ĭolima is a VM based on Lima providing container runtimes in MacOS/Linux. As Docker updated their service agreements on August 31st, 2021, I needed to find an open-source or a free alternative to Docker Desktop, leading to Colima. Being a software engineer for some years, I have often used Docker Desktop in my career to manage containerized applications.
