Trove-Integration

Trove-Integration/redstack setup

Requirements on ubuntu 14.04 before running ./redstack install

• sudo apt-get install python-pip
• sudo apt-get install python-dev
• sudo apt-get install mysql-server (set mysql server root password to e1a2c042c828d3566d0a which is the same password as in devstack/localrc)
• clone Trove-integration git clone https://github.com/openstack/trove-integration.git
• Now run ./redstack install
• If redstack install was successful you can now run ./redstack kick-start mysql to add the ubuntu-mysql image

After redstack runs it automatically generates the devstack/localrc file and enables the trove services

 ENABLED_SERVICES+=,trove,tr-api,tr-tmgr,tr-cond'

Common Errors

• trove-api (tr-api from screen) fails to start with error:

 2015-01-15 10:29:07.214 TRACE root RuntimeError: Could not bind to 0.0.0.0:8779 after trying for 30 seconds
 2015-01-15 10:29:07.214 TRACE root

This typically means there are multiple trove-api processes running and a previous unstack didn't clean up everything. To fix this:

1. Kill the tr-api process from screen -x stack by pressing ctrl-c
2. Exit out of screen and run ps afx | grep trove-api
3. If there any trove-api processes then kill all the trove-api proceses (kill <process-id>)
4. Go back to screen -x stack, navigate to tr-api process and restart process (press up arrow to get last run command which will be the command to restart tr-api)

Enable Neutron support on Trove-Integration/redstack

• Set ENABLE_NEUTRON=true on redstack.rc which will set the neutron enabled services and disable the nova network
• When enabling neutron on redstack the devstack/localrc will now contain the following:

 ENABLED_SERVICES+=,neutron,q-svc,q-agt,q-dhcp,q-l3,q-meta
 disable_service n-net'

Adding TripleO-Image-Elements to Trove-Integration/redstack images

When you run ./redstack kick-start mysql it creates an image under ~/images/ubuntu-mysql from Trove-Integration/scripts/elements/ubuntu-mysql. If you want to add an element to ubuntu-mysql such as os-apply-config (https://github.com/openstack/tripleo-image-elements/tree/master/elements/os-apply-config) you need to add the variable EXTRA_ELEMENTS to the trove-integration/scripts/redstack.rc file. By default redstack kick-start should be able to find os-apply-config because it clones all of the tripleo-image-elements. The Elements path redstack kick-start uses is ELEMENTS_PATH=$REDSTACK_SCRIPTS/files/elements:$PATH_TRIPLEO_ELEMENTS/elements

• Ex: EXTRA_ELEMENTS="os-apply-config" # adding single element
• Ex: EXTRA_ELEMENTS="os-apply-config os-refresh-config" # adding multiple elements is space delimited

Now when running ./redstack kick-start mysql it will add the os-apply-config element to the ubuntu-mysql image.

• Now you can add the folder os-apply-config to the Trove-Integration/scripts/elements/ubuntu-mysql image to add custom configuration files etc.
• Adding the file (foo.conf) and folders (os-apply-config/etc/init) to the element ubuntu-mysql (ubuntu-mysql/os-apply-config/etc/init/foo.conf) will add the file foo.conf to /etc/init when doing a trove create with the new image ./redstack kick-start mysql built.

Rebuilding image

Once an image is created you will need to do nova image-delete and delete the ~/images/ubuntu-mysql file in order to have ./redstack kick-start mysql build the image again. If you do not, the existing image ubuntu-mysql will be used again.
