garden job from garden-runc/1.19.31

Github source: acf58c8 or master branch

Properties

bpm

enabled

Use bpm. NOTE: this requires a recreate when enabling for the first time, otherwise old containers may be left running. NOTE: When this property is enabled, containers won’t survive a restart of the garden job. This is why garden.destroy_containers_on_start should be set to avoid leaking container state.

Default
false

garden

additional_bpm_volumes

An array of shared writable volumes which will be mounted into the BPM container. Submounts from all mount namespaces in a volume are visible in all containers that have the volume mounted in. Note: Can only be used when deploying with BPM to mount in existing volumes.

Default
[]

additional_dns_servers

Additional DNS servers to be used in containers; extends those used on the host or those set by dns_servers property

Default
[]

additional_host_entries

Additional hosts file entries to be used in containers.

Default
[]

allow_host_access

A boolean stating whether or not containers started on this host should be able to reach this host. Changing the value on an existing deployment requires a recreate

Default
false

apparmor_profile

AppArmor profile to use for unprivileged container processes

Default
garden-default

cleanup_process_dirs_on_wait

Default
false

Default
0

CPU percentage entitled to a container for a single CPU share. 0 means that the entitlement will be automatically calculated so that the CPU resources get optimally distributed.

Default
0

experimental_cpu_throttling

(Under development) Number of seconds between each CPU throttling check

Default
15

experimental_rootless_mode

Default
info

max_containers

Maximum container capacity to advertise. It is not recommended to set this larger than 250.

Default
250

network_mtu

Maximum network transmission unit length in bytes. Defaults to the mtu of the interface that the host uses for outbound connections. Max allowed value is 1500. Changed value applies only to newly created containers.

tcp_keepalive_probes

Sets the net.ipv4.tcp_keepalive_probes kernel parameter in containers. If not specified, the value from the linux init_net namespace is used.

tcp_keepalive_time

grootfs

dropsonde_port

Local metron agent’s port.

Default
3457

experimental_direct_io

Enable the DIRECT_IO flag on the loop device associated with the GrootFS store. This should reduce memory and processing overheads by eliminating double caching of the store filesystem

Default
false

graph_cleanup_threshold_in_mb

Default
-1

Default
[]

log_level

Log level for grootfs - can be debug, info, error or fatal.

Default
info

reserved_space_for_other_jobs_in_mb

Amount of space that will be kept free for other jobs. The GrootFS store will be able to grow up to a maximum size of its disk minus this reserved space. Where the reserved space does not allow sufficient size for GrootFS to store container images and root filesystems (currently 15GB), the limit will be a soft limit, and garbage collection will attempt to keep disk space available for other jobs. -1 disables GC and allows GrootFS to potentially use the whole disk.

Default
15360

skip_mount

Do not mount image root filesystem automatically, just return the mount information.

Default
false

tls

ca_cert

PEM-encoded tls client CA certificate for asset upload/download

cert
