Containers Containerd

config_version | string

Default: v1

(Use carefully, v2 is only tested for nvidia gpu operator) Use value "v2" for this config parameter to enable new configuration format. Config file is parsed as version 1 by default. Version 2 uses long plugin names, i.e. "io.containerd.grpc.v1.cri" vs "cri".

custom-registry-ca | string

Base64 encoded Certificate Authority (CA) bundle. Setting this config allows container runtimes to pull images from registries with TLS certificates signed by an external CA.

custom_registries | string

Default: []

Registry endpoints and credentials. Setting this config allows Kubelet to pull images from registries where auth is required. The value for this config must be a JSON array of credential objects, like this: e.g.: [{"host": "my.registry:port", "username": "user", "password": "pass"}] Credential Object Parameters: `url: REQUIRED str` the URL to the registry, include the port if not it isn't implied from the schema. e.g: "url": "https://my.registry:8443"; e.g: "url": "http://my.registry"; host: OPTIONAL str - defaults to auto-generated from the url could be registry host address or a name e.g.: myregistry.io:9000, 10.10.10.10:5432 e.g.: myregistry.io, myregistry Note: It will be derived from `url` if not provided. e.g.: "url": "http://10.10.10.10:8000"; --> "host": "10.10.10.10:8000" username: OPTIONAL str - default '' password: OPTIONAL str - default '' Used by containerd for basic authentication to the registry. ca_file: OPTIONAL str - default '' cert_file: OPTIONAL str - default '' key_file: OPTIONAL str - default '' For ssl/tls communication these should be a base64 encoded file e.g.: "ca_file": "'"$(base64 -w 0 < my.custom.registry.pem)"'" insecure_skip_verify: OPTIONAL bool - default false For situatations where the registry has self-signed or expired certs and a quick work-around is necessary. e.g.: "insecure_skip_verify": true example config) juju config containerd custom_registries='[{ "url": "https://registry.example.com";, "ca_file": "'"$(base64 -w 0 < ~/my.custom.ca.pem)"'", "cert_file": "'"$(base64 -w 0 < ~/my.custom.cert.pem)"'", "key_file": "'"$(base64 -w 0 < ~/my.custom.key.pem)"'", }]'

disable-juju-proxy | boolean

Ignore juju-http(s) proxy settings on this charm. If set to true, all juju https proxy settings will be ignored

enable-cgroups | boolean

Enable GRUB cgroup overrides cgroup_enable=memory swapaccount=1. WARNING changing this option will reboot the host - use with caution on production services.

gpu_driver | string

Default: auto

Override GPU driver installation. Options are "auto", "nvidia", "none".

http_proxy | string

URL to use for HTTP_PROXY to be used by Containerd. Useful in egress-filtered environments where a proxy is the only option for accessing the registry to pull images.

https_proxy | string

URL to use for HTTPS_PROXY to be used by Containerd. Useful in egress-filtered environments where a proxy is the only option for accessing the registry to pull images.

no_proxy | string

Comma-separated list of destinations (either domain names or IP addresses) which should be accessed directly, rather than through the proxy defined in http_proxy or https_proxy. Must be less than 2023 characters long.

nvidia_apt_key_urls | string

Default: https://nvidia.github.io/nvidia-container-runtime/gpgkey https://developer.download.nvidia.com/compute/cuda/repos/{id}{version_id_no_dot}/x86_64/7fa2af80.pub

Space-separated list of APT GPG key URLs to add when using Nvidia GPUs. Supported template options: {id}: OS release ID, e.g. "ubuntu" {version_id}: OS release version ID, e.g. "20.04" {version_id_no_dot}: OS release version ID with no dot, e.g. "2004"

nvidia_apt_packages | string

Default: cuda-drivers nvidia-container-runtime

Space-separated list of APT packages to install when using Nvidia GPUs.

nvidia_apt_sources | string

Default: deb https://nvidia.github.io/libnvidia-container/{id}{version_id}/$(ARCH) / deb https://nvidia.github.io/nvidia-container-runtime/{id}{version_id}/$(ARCH) / deb http://developer.download.nvidia.com/compute/cuda/repos/{id}{version_id_no_dot}/x86_64 /

Newline-separated list of APT sources to add when using Nvidia GPUs. Supported template options: {id}: OS release ID, e.g. "ubuntu" {version_id}: OS release version ID, e.g. "20.04" {version_id_no_dot}: OS release version ID with no dot, e.g. "2004"

runtime | string

Default: auto

Set a custom containerd runtime. Set "auto" to select based on hardware.

shim | string

Default: containerd-shim

Set a custom containerd shim.
