Install Trove in DevStack
=========================
This page describes how to set up a working development
environment that can be used in deploying Trove on latest releases
of Ubuntu.
Following these instructions will allow you to have a fully functional Trove
environment using the DevStack on Ubuntu 16.04 or 18.04.
Config DevStack with Trove
~~~~~~~~~~~~~~~~~~~~~~~~~~
Trove can be enabled in devstack by using the plug-in based interface it
offers.
.. note::
The following steps have been fully verified both on Ubuntu 16.04 and 18.04.
Start by cloning the devstack repository using a non-root user(the default user
is ``ubuntu``) and change to devstack directory:
.. code-block:: console
git clone https://opendev.org/openstack/devstack
cd devstack/
Create the ``local.conf`` file with the following minimal devstack
configuration, change the ``HOST_IP`` to your own devstack host IP address:
.. code-block:: ini
[[local|localrc]]
RECLONE=False
HOST_IP=<your-host-ip-here>
enable_plugin trove https:/opendev.org/openstack/trove
LIBS_FROM_GIT+=,python-troveclient
DATABASE_PASSWORD=password
ADMIN_PASSWORD=password
SERVICE_PASSWORD=password
SERVICE_TOKEN=password
RABBIT_PASSWORD=password
LOGFILE=$DEST/logs/stack.sh.log
VERBOSE=True
LOG_COLOR=False
LOGDAYS=1
IPV4_ADDRS_SAFE_TO_USE=10.111.0.0/26
FIXED_RANGE=10.111.0.0/26
NETWORK_GATEWAY=10.111.0.1

Take a look at the
`options <https://opendev.org/openstack/trove/src/branch/master/devstack/settings>`_
you could use to customize the Trove installation.
Running devstack
~~~~~~~~~~~~~~~~
Run the ``stack.sh`` script:
.. code-block:: console
./stack.sh
After it completes, you can see there is a MySQL datastore available to create
Trove instance:
.. code-block:: console
$ openstack datastore version list mysql
+--------------------------------------+------------------+
| ID | Name |
+--------------------------------------+------------------+

| f81a8448-2f6e-4746-8d97-866ab7dcccee | inactive_version |
+--------------------------------------+------------------+
Create your first Trove instance
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. Switch to a non-admin user, choose a Nova flavor ID for the Trove
instance.
.. code-block:: console
$ source ~/devstack/openrc demo demo
$ openstack flavor list

Manual Trove Installation
=========================
Objectives
~~~~~~~~~~
This document provides a step-by-step guide for manual installation of Trove
with an existing OpenStack environment for development purposes.
This document will not cover OpenStack setup for other services.
Requirements
~~~~~~~~~~~~
A running OpenStack environment installed on Ubuntu 16.04 or 18.04 LTS is
required, including the following components:
- Compute (Nova)
- Image Service (Glance)
- Identity (Keystone)
- Network (Neutron)
- If you want to provision databases on block-storage volumes, you also need
Block Storage (Cinder)
- If you want to do backup/restore or replication, you also need Object Storage
(Swift)
- AMQP service (RabbitMQ or QPID)
- MySQL (SQLite, PostgreSQL) database
Networking requirements
-----------------------
Trove makes use of an "Management Network" that the controller uses to talk to
trove instance and vice versa. All the trove instance that Trove deploys will
have interfaces and IP addresses on this network. Therefore, its important
that the subnet deployed on this network be sufficiently large to allow for the
maximum number of trove instance and controllers likely to be deployed
throughout the lifespan of the cloud installation.
You must also create a Neutron security group which will be applied to trove
instance port created on the management network. The cloud admin has full
control of the security group, e.g it can be helpful to allow SSH access to the
trove instance from the controller for troubleshooting purposes (ie. TCP port
22), though this is not strictly necessary in production environments.
Finally, you need to add routing or interfaces to this network so that the
Trove controller is able to communicate with Nova servers on this network.

Objectives
==========
This document provides a step-by-step guide for manual installation of Trove with
an existing OpenStack environment for development purposes.
This document will not cover:
- OpenStack setup
- Trove service configuration
Requirements
============
A running OpenStack environment is required, including the following components:
- Compute (Nova)
- Image Service (Glance)
- Identity (Keystone)
- Network (Neutron)
- If you want to provision datastores on block-storage volumes, you also will need Block Storage (Cinder)
- If you want to do backup/restore and replication, you will also need Object Storage (Swift)
- An environment with a freshly installed Ubuntu 16.04 LTS to run Trove services.
This will be referred to as "local environment"
- AMQP service (RabbitMQ or QPID)
- MySQL (SQLite, PostgreSQL) database for Trove's internal needs, accessible from the local environment
- Certain OpenStack services must be accessible from VMs:
- Swift
- VMs must be accessible from local environment for development/debugging purposes
- OpenStack services must be accessible directly from the local environment, such as:
- Nova
- Cinder
- Swift
- Heat
Installation
============
-----------
Gather info
-----------
The following information about the existing environment is required:
- Keystone host and port(s)
- OpenStack administrator's username, tenant name and password
- Nova URL
- Cinder URL
- Swift URL
- Heat URL
- AMQP connection credentials (server URL, user, password)
- Trove's controller backend connection string (MySQL, SQLite, PostgreSQL)

$ cd setuptools-{{latest}}
$ python setup.py install --user
Use latest pip:
Go https://pypi.org/project/pip, download the latest source pip, and move it under ~
.. code-block:: bash
$ tar xfvz pip-{{latest}}.tar.gz
$ cd pip-{{latest}}
$ python setup.py install --user
Note '--user' above -- we installed packages in user's home dir, in $HOME/.local/bin, so we need to add it to path:
.. code-block:: bash
$ echo PATH="$HOME/.local/bin:$PATH" >> ~/.profile
$ . ~/.profile
Install virtualenv, create environment and activate it:
.. code-block:: bash
$ pip install virtualenv --user

Install Trove
=============
First, install the requirements:
.. code-block:: bash
$ cd ~/trove
$ pip install -r requirements.txt -r test-requirements.txt
Then, install Trove:
.. code-block:: bash
$ sudo python setup.py develop
Finally, install the Trove client:
.. code-block:: bash
$ cd ~/python-troveclient
$ sudo python setup.py develop
$ cd ~
Other required OpenStack clients (python-novaclient, python-keystoneclient, etc.) should already be installed as part of the Trove requirements.
---------------------------
Prepare Trove for OpenStack
---------------------------
You will first need to create a tenant called 'trove_for_trove_usage'.
Next, create users called 'regular_trove_user' and 'admin_trove_user' —using 'trove' as the password. These are the accounts used by the Trove service.
Additionally, you will need to register Trove as an OpenStack service and its endpoints:
.. code-block:: bash
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity project create trove_for_trove_usage
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity user create regular_trove_user --project trove_for_trove_usage --password-prompt
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity user create admin_trove_user --project trove_for_trove_usage --password-prompt
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity role add --user admin_trove_user --project trove_for_trove_usage admin
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity service create --name trove --description "Database" database
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity endpoint create --region RegionOne database public 'http://<EnvironmentPublicIP>:<EnvironmentPort>/v1.0/$(tenant_id)s'
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity endpoint create --region RegionOne database admin 'http://<EnvironmentPublicIP>:<EnvironmentPort>/v1.0/$(tenant_id)s'
$ openstack --os-username <OpenStackAdminUsername> --os-password <OpenStackAdminPassword> --os-project-name <OpenStackAdminProject> --os-domain-name <OpenstackDomainName> --os-auth-url http://<KeystoneIP>/identity endpoint create --region RegionOne database internal 'http://<EnvironmentPublicIP>:<EnvironmentPort>/v1.0/$(tenant_id)s'
Where <EnvironmentPublicIP> and <EnvironmentPort> are the IP address and Port of the server where Trove was installed. This IP should be reachable from any hosts that will be used to communicate with Trove.
Prepare Trove configuration files
=================================
There are several configuration files for Trove:
- api-paste.ini and trove.conf — For trove-api service
- trove-guestagent.conf — For trove-guestagent service
- <datastore_manager>.cloudinit — Userdata for VMs during provisioning
Cloud-init scripts are userdata that is being used for different datastore types like mysql/percona, cassandra, mongodb, redis, couchbase while provisioning new compute instances.
Samples of the above are available in ~/trove/etc/trove/ as \*.conf.sample files.
If a clean Ubuntu image is used as the source image for Trove instances, the cloud-init script must install and run guestagent in the instance.
As an alternative, one may consider creating a custom image with pre-installed and pre-configured Trove in it.
Source images
=============
As the source image for Trove instances, we will use a Trove-compatible Ubuntu image.
Build your own Trove images, Then run the following steps:
.. code-block:: bash
$ export DATASTORE_TYPE="mysql"
$ glance --os-username admin_trove_user --os-password trove --os-tenant-name trove_for_trove_usage --os-auth-url http://<KeystoneIP>:<KeystoneAdminPort>/v2.0 image-create --name trove-image --is-public True --container-format ovf --disk-format qcow2 --file ${DATASTORE_TYPE}.qcow2
At this step please remember the image ID or store it in an environment variable (IMAGEID).
.. code-block:: bash
$ glance --os-username trove --os-password trove --os-tenant-name trove --os-auth-url http://<KeystoneIP>:<KeystoneAdminPort>/v2.0
image-create --name trove-image --is-public true --container-format ovf --disk-format qcow2 --owner trove < precise.qcow2
$ export IMAGEID=<glance_image_id>
Cloud-init scripts
==================
-------------------
Cloud-init location
-------------------
By default, trove-taskmanager will look at /etc/trove/cloudinit for <datastore_manager>.cloudinit.
------------------
Cloud-init content
------------------
Each cloud-init script for Trove-compatible images should contain:
- Trove installation
Custom images with Trove code inside
====================================
*To be added*
Prepare the database
====================
Create the Trove database schema:
- Connect to the storage backend (MySQL, PostgreSQL)
- Create a database called `trove` (this database will be used for storing Trove ORM)
- Compose connection string. Example: mysql+pymysql://<user>:<password>@<backend_host>:<backend_port>/<database_name>
Initialize the database
=======================
Once the database for Trove is created, its structure needs to be populated.
.. code-block:: bash
$ trove-manage db_sync
Setup Trove Datastores
======================
---------
Datastore
---------
A Datastore is a data structure that describes a set of Datastore Versions, which consists of::
- ID -- simple auto-generated UUID
- Name -- user-defined attribute, actual name of a datastore
- Datastore Versions
Example::
- mysql, cassandra, redis, etc.
-----------------
Datastore Version
-----------------
A Datastore Version is a data structure that describes a version of a specific database pinned to datastore, which consists of::
- ID — Simple auto-generated UUID
- Datastore ID — Reference to Datastore
- Name — User-defined attribute, actual name of a database version
- Datastore manager — trove-guestagent manager that is used for datastore management
- Image ID — Reference to a specific Glance image ID
- Packages — Operating system specific packages that would be deployed onto datastore VM
- Active — Boolean flag that defines if version can be used for instance deployment or not
Example::
- ID - edb1d22a-b66d-4e86-be60-756240439272
- Datastore ID - 9c3d890b-a2f2-4ba5-91b2-2997d0791502
- Name - mysql-5.7
- Datastore manager - mysql
- Image ID - d73a402-3953-4721-8c99-86fc72e1cb51
- Packages - mysql-server=5.7, percona-xtrabackup=2.4
- Active - True
--------------------------------------------
Datastore and Datastore Version registration
--------------------------------------------
To register a datastore, you must execute:
.. code-block:: bash
$ export DATASTORE_TYPE="mysql" # available options: mysql, mongodb, postgresql, redis, cassandra, couchbase, couchdb, db2, vertica, etc.
$ export DATASTORE_VERSION="5.7" # available options: for cassandra 2.0.x, for mysql: 5.x, for mongodb: 2.x.x, etc.
$ export PACKAGES="mysql-server-5.7" # available options: cassandra=2.0.9, mongodb=2.0.4, etc
$ export IMAGEID="9910350b-77e3-4790-86be-b971d0cf9175" # Glance image ID of the relevant Datastore version (see Source images section)
$ trove-manage datastore_update ${DATASTORE_TYPE} ""
$ trove-manage datastore_version_update ${DATASTORE_TYPE} ${DATASTORE_VERSION} ${DATASTORE_TYPE} ${IMAGEID} ${PACKAGES} 1
$ trove-manage datastore_update ${DATASTORE_TYPE} ${DATASTORE_VERSION}
=========
Run Trove
=========
Trove services configuration and tuning
=======================================
*To be added*
Starting Trove services
=======================
Run trove-api:
.. code-block:: bash
$ trove-api --config-file=${TROVE_CONF_DIR}/trove.conf &
Run trove-taskmanager:
.. code-block:: bash
$ trove-taskmanager --config-file=${TROVE_CONF_DIR}/trove.conf &
Run trove-conductor:
.. code-block:: bash
$ trove-conductor --config-file=${TROVE_CONF_DIR}/trove.conf &
=================
Trove interaction
=================
Keystonerc
==========
You need to build a `keystonerc` file that contains data to simplify the auth processes while using the Trove client:
.. code-block:: bash
export OS_PROJECT_NAME=trove
export OS_USERNAME=regular_trove_user
export OS_PASSWORD=<UserPassword>
export OS_AUTH_URL="http://<KeystoneIP>/identity"
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
Trove deployment verification
=============================
First you need to execute:
.. code-block:: bash
$ . keystonerc
To see `help` for a specific command:
.. code-block:: bash
$ trove help <command>
To create an instance:
.. code-block:: bash
$ trove create <name> <flavor>
[--size <size>] [--volume_type <volume_type>]
[--databases <database> [<database> ...]]
[--users <user:password> [<user:password> ...]]
[--backup <backup>]
[--availability_zone <availability_zone>]
[--datastore <datastore>]
[--datastore_version <datastore_version>]
[--nic <net-id=<net-uuid>,v4-fixed-ip=<ip-addr>,port-id=<port-uuid>>]
[--configuration <configuration>]
[--replica_of <source_instance>] [--replica_count <count>]
[--module <module>] [--locality <policy>]
===============
Troubleshooting
===============
No instance IPs in the output of 'trove show <instance_id>'
===========================================================
If the Trove instance was successfully created, is showing ACTIVE state and working, yet there is no IP address for the instance shown in the output of 'trove show <instance_id>, then confirm the following lines are added to trove.conf ::
network_label_regex = ^NETWORK_NAME$
where NETWORK_NAME should be replaced with real name of the network to which the instance is connected to.
To decide which network would you like to attach a Trove instance to, run the following command:
.. code-block:: bash
$ openstack network list
One possible way to find the network name is to execute the 'nova list' command. The output will list all OpenStack instances for the tenant, including network information. Look for ::
NETWORK_NAME=IP_ADDRESS
Additional information
======================
