Options for Juju Charms

 

Each Contrail Charm has a specific set of options. The options you choose depend on the charms you select. The following tables list the various options you can choose:

  • Options for contrail-agent Charms.

    Table 1: Options for contrail-agent

    Option

    Default option

    Description

    physical-interface

    Specify the interface where you want to install vhost0 on. If you do not specify an interface, vhost0 is installed on the default gateway interface.

    vhost-gateway

    auto

    Specify the gateway for vhost0. You can enter either an IP address or the keyword (auto) to automatically set a gateway based on the existing vhost routes.

    remove-juju-bridge

    true

    To install vhost0 directly on the interface, enable this option to remove any bridge created to deploy LXD/LXC and KVM workloads.

    dpdk

    false

    Specify DPDK vRouter.

    dpdk-driver

    uio_pci_generic

    Specify DPDK driver for the physical interface.

    dpdk-hugepages

    70%

    Specify the percentage of huge pages reserved for DPDK vRouter and OpenStack instances.

    dpdk-coremask

    1

    Specify the vRouter CPU affinity mask to determine on which CPU the DPDK vRouter will run.

    dpdk-main-mempool-size

    Specify the main packet pool size.

    dpdk-pmd-txd-size

    Specify the DPDK PMD Tx Descriptor size.

    dpdk-pmd-rxd-size

    Specify the DPDK PMD Rx Descriptor size.

    docker-registry

    opencontrailnightly

    Specify the URL of the docker-registry.

    docker-registry-insecure

    false

    Specify if the docker-registry should be configured.

    docker-user

    Log in to the docker registry.

    docker-password

    Specify the docker-registry password.

    image-tag

    latest

    Specify the docker image tag.

    log-level

    SYS_NOTICE

    Specify the log level for Contrail services.

    Options: SYS_EMERG, SYS_ALERT, SYS_CRIT, SYS_ERR, SYS_WARN, SYS_NOTICE, SYS_INFO, SYS_DEBUG

    http_proxy

    Specify URL.

    https_proxy

    Specify URL.

    kernel-hugepages-1g

    Parameter not enabled by default.

    Note: 2MB huge pages for kernel-mode vRouters are enabled by default.

    Specify the number of 1G huge pages for use with vRouters in kernel mode.

    You can enable huge pages to avoid compute node reboots during software upgrades.

    This parameter must be specified at initial deployment. It cannot be modified in an active deployment. If you need to migrate to huge page usage in an active deployment, use 2MB huge pages if suitable for your environment.

    We recommend allotting 2GB of memory—either using the default 1024x2MB huge page size setting or the 2x1GB size setting—for huge pages. Other huge page size settings should only be set by expert users in specialized circumstances.

    1GB and 2MB huge pages cannot be enabled simultaneously in environments using Juju. If you are using this command parameter to enable 1GB huge pages, you must also disable 2MB huge pages. 2MB huge pages can be disabled by entering the juju config contrail-agent kernel-hugepages-2m=““ command with an empty value.

    A compute node reboot is required to enable a huge page setting configuration change. After this initial reboot, compute nodes can complete software upgrades without a reboot.

    Huge pages are disabled for kernel-mode vRouters if the kernel-hugepages-1g and the kernel-hugepages-2m options are not set.

    This parameter was introduced in Contrail Networking Release 2005.

    kernel-hugepages-2m

    1024

    Specify the number of 2MB huge pages for use with vRouters in kernel mode. Huge pages in Contrail Networking are used primarily to allocate flow and bridge table memory within the vRouter. Huge pages for kernel-mode vRouters provide enough flow and bridge table memory to avoid compute node reboots to complete future Contrail Networking software upgrades.

    1024x2MB huge pages are configured by default starting in Contrail Networking Release 2005. A compute node reboot is required to enable a kernel-mode vRouter huge page setting configuration change, however, so this huge page setting is not enabled on a compute node until the compute node is rebooted.

    After a compute node is rebooted to enable a vRouter huge page setting, compute nodes can complete software upgrades without a reboot.

    We recommend allotting 2GB of memory—either using the default 1024x2MB huge page size setting or the 2x1GB size setting—for kernel-mode vRouter huge pages. Other huge page size settings should only be set by expert users in specialized circumstances.

    1GB and 2MB huge pages cannot be enabled simultaneously in environments using Juju. If you are using this command parameter to enable 2MB huge pages, you must also disable 1GB huge pages. 1GB huge pages are disabled by default and can also be disabled by entering the juju config contrail-agent kernel-hugepages-1g=““ command with an empty value. 1GB huge pages can only be enabled at initial deployment; you cannot initially enable 1GB huge pages in an active deployment.

    Huge pages are disabled for kernel-mode vRouters if the kernel-hugepages-1g and the kernel-hugepages-2m options are not set.
