Swift in Kolla
|
|
==============
|
|
|
|
Overview
|
|
--------
|
|
Kolla can deploy a full working Swift setup in either a AIO or multi node setup.
|
|
|
|
Prerequisites
|
|
-------------
|
|
Before running Swift we need to generate "rings", which are binary compressed files that at a high
|
|
level let the various Swift services know where data is in the cluster. We hope to automate this
|
|
process in a future release.
|
|
|
|
Swift also expects block devices to be available and partitioned on the host, which Swift uses in
|
|
combination with the rings to store data. Swift demos commonly just use directories created under
|
|
/srv/node to simulate these devices. In order to ease "out of the box" testing of Kolla, we offer a
|
|
similar setup with a data container. *Note*, data containers are very inefficient for this purpose.
|
|
In production setups operators will want to provision disks according to the Swift operator guide,
|
|
which can then be added the rings and used in Kolla.
|
|
|
|
For an AIO setup, the following commands can be used, locally, to generate rings containing the data
|
|
container directories:
|
|
|
|
::
|
|
|
|
export KOLLA_INTERNAL_ADDRESS=1.2.3.4
|
|
export KOLLA_BASE_DISTRO=centos
|
|
export KOLLA_INSTALL_TYPE=binary
|
|
|
|
# Object ring
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base \
|
|
swift-ring-builder /etc/kolla/config/swift/object.builder create 10 3 1
|
|
|
|
for partition in sdb1 sdb2 sdb3; do
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base swift-ring-builder \
|
|
/etc/kolla/config/swift/object.builder add z1-${KOLLA_INTERNAL_ADDRESS}:6000/${partition} 1;
|
|
done
|
|
|
|
# Account ring
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base \
|
|
swift-ring-builder /etc/kolla/config/swift/account.builder create 10 3 1
|
|
|
|
for partition in sdb1 sdb2 sdb3; do
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base swift-ring-builder \
|
|
/etc/kolla/config/swift/account.builder add z1-${KOLLA_INTERNAL_ADDRESS}:6001/${partition} 1;
|
|
done
|
|
|
|
# Container ring
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base \
|
|
swift-ring-builder /etc/kolla/config/swift/container.builder create 10 3 1
|
|
|
|
for partition in sdb1 sdb2 sdb3; do
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base swift-ring-builder \
|
|
/etc/kolla/config/swift/container.builder add z1-${KOLLA_INTERNAL_ADDRESS}:6002/${partition} 1;
|
|
done
|
|
|
|
for ring in object account container; do
|
|
docker run \
|
|
-v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
|
|
kollaglue/${KOLLA_BASE_DISTRO}-${KOLLA_INSTALL_TYPE}-swift-base swift-ring-builder \
|
|
/etc/kolla/config/swift/${ring}.builder rebalance;
|
|
done
|
|
|
|
Similar commands can be used for multinode, you will just need to run the 'add' step for each IP
|
|
in the cluster.

Deploying
|
|
---------
|
|
Once the rings are in place, deploying Swift is the same as any other Kolla Ansible service. Below
|
|
is the minimal command to bring up Swift AIO, and it's dependencies:
|
|
|
|
::
|
|
|
|
ansible-playbook \
|
|
-i ansible/inventory/all-in-one \
|
|
-e @/etc/kolla/globals.yml \
|
|
-e @etc/kolla/passwords.yml \
|
|
ansible/site.yml \
|
|
--tags=rabbitmq,mariadb,keystone,swift
|
|
|
|
Validation
|
|
----------
|
|
A very basic smoke test:
|
|
|
|
::
|
|
|
|
