Overview:
Build and test kata containers from source
Optionally set kata-containers and tests repo and branch as exported variables before running
e.g. export katacontainers_repo=github.com/stevenhorsman/kata-containers && export katacontainers_branch=kata-ci-from-fork && export tests_repo=github.com/stevenhorsman/tests && export tests_branch=kata-ci-from-fork && ~/${script_name} build_and_install_all
Usage:
${script_name} [options] <command>
Commands:
- agent_create_container: Run CreateContainer command against the agent with agent-ctl
- agent_pull_image: Run PullImage command against the agent with agent-ctl
- all: Build and install everything, test kata with containerd and capture the logs
- build_and_add_agent_to_rootfs: Builds the kata-agent and adds it to the rootfs
- build_and_install_all: Build and install everything
- build_and_install_rootfs: Builds and installs the rootfs image
- build_kata_runtime: Build and install the kata runtime
- build_cloud_hypervisor Checkout, patch, build and install Cloud Hypervisor
- build_qemu: Checkout, patch, build and install QEMU
- configure: Configure Kata to use rootfs and enable debug
- connect_to_ssh_demo_pod: Ssh into the ssh demo pod, showing that the decryption succeeded
- copy_signature_files_to_guest Copies signature verification files to guest
- create_rootfs: Create a local rootfs
- crictl_create_cc_container Use crictl to create a new busybox container in the kata cc pod
- crictl_create_cc_pod Use crictl to create a new kata cc pod
- crictl_delete_cc Use crictl to delete the kata cc pod sandbox and container in it
- help: Display this help
- init_kubernetes: initialize a Kubernetes cluster on this system
- initialize: Install dependencies and check out kata-containers source
- install_guest_kernel: Setup, build and install the guest kernel
- kubernetes_create_cc_pod: Create a Kata CC runtime busybox-based pod in Kubernetes
- kubernetes_create_ssh_demo_pod: Create a Kata CC runtime pod based on the ssh demo
- kubernetes_delete_cc_pod: Delete the Kata CC runtime busybox-based pod in Kubernetes
- kubernetes_delete_ssh_demo_pod: Delete the Kata CC runtime pod based on the ssh demo
- open_kata_shell: Open a shell into the kata runtime
- rebuild_and_install_kata: Rebuild the kata runtime and agent and build and install the image
- shim_pull_image: Run PullImage command against the shim with ctr
- test_capture_logs: Test using kata with containerd and capture the logs in the user's home directory
- test: Test using kata with containerd
Options:
-d: Enable debug
