--- ## Uncomment this if you want to force overlay/overlay2 as docker storage driver ## Please note that overlay2 is only supported on newer kernels # docker_storage_options: -s overlay2 ## Enable docker_container_storage_setup, it will configure devicemapper driver on Centos7 or RedHat7. docker_container_storage_setup: false ## It must be define a disk path for docker_container_storage_setup_devs. ## Otherwise docker-storage-setup will be executed incorrectly. # docker_container_storage_setup_devs: /dev/vdb ## Uncomment this if you want to change the Docker Cgroup driver (native.cgroupdriver) ## Valid options are systemd or cgroupfs, default is systemd # docker_cgroup_driver: systemd ## Only set this if you have more than 3 nameservers: ## If true Kubespray will only use the first 3, otherwise it will fail docker_dns_servers_strict: false # Path used to store Docker data docker_daemon_graph: "/var/lib/docker" ## Used to set docker daemon iptables options to true docker_iptables_enabled: "false" # Docker log options # Rotate container stderr/stdout logs at 50m and keep last 5 docker_log_opts: "--log-opt max-size=50m --log-opt max-file=5" # define docker bin_dir docker_bin_dir: "/usr/bin" # keep docker packages after installation; speeds up repeated ansible provisioning runs when '1' # kubespray deletes the docker package on each run, so caching the package makes sense docker_rpm_keepcache: 1 ## An obvious use case is allowing insecure-registry access to self hosted registries. ## Can be ipaddress and domain_name. ## example define 172.19.16.11 or mirror.registry.io # docker_insecure_registries: # - mirror.registry.io # - 172.19.16.11 ## Add other registry,example China registry mirror. # docker_registry_mirrors: # - https://registry.docker-cn.com # - https://mirror.aliyuncs.com ## If non-empty will override default system MountFlags value. ## This option takes a mount propagation flag: shared, slave ## or private, which control whether mounts in the file system ## namespace set up for docker will receive or propagate mounts ## and unmounts. Leave empty for system default # docker_mount_flags: ## A string of extra options to pass to the docker daemon. ## This string should be exactly as you wish it to appear. # docker_options: ""
