oci-defaults

Settings related to orchestrated containers for overriding the OCI runtime spec defaults (settings.oci-defaults.*).

Topic list

Setting list for settings.oci-defaults

Topics

Capabilities Settings

Capabilities for the runtime process. These correspond to the object capabilities in the runtime spec.

Settings

Resource Limits Settings

Resource limits for the runtime process. These correspond to the object rlimit in the runtime spec.

Unusual among Bottlerocket settings, individual key/values will not validate. You must provide both hard-limit and soft-limit for any given resource limit setting at the same time. Consequently, using dot-notation expressions to change resource limits is not possible (e.g. apiclient set settings.oci-defaults.resource-limits.max-locked-memory.hard-limit=9223372 will fail). You can use TOML configuration format or the same structure expressed as JSON to set both keys simultaneously.

# Setting a limit
[settings.oci-defaults.resource-limits.max-core-file-size]
soft-limit = 100000000
hard-limit = 1000000000

# Removing a hard limit
[settings.oci-defaults.resource-limits.max-locked-memory]
soft-limit = 100000000
hard-limit = "unlimited"
