Log location
|
|
~~~~~~~~~~~~
|
|
|
|
By default, logs are sent to stdout. Consider how to set up the log files.
|
|
|
|
Murano API + Engine
|
|
-------------------
|
|
|
|
To define a file where to store logs, use the ``log_file`` option in the
|
|
:file:`murano.conf` file. You can provide an absolute or a relative path.
|
|
|
|
To enable a detailed log file configuration, set up :file:`logging.conf`.
|
|
The example is provided in :file:`etc/murano` directory. The log configuration
|
|
file location is set with the ``log_config_append`` option in the murano
|
|
configuration file.
|
|
|
|
Murano applications
|
|
-------------------
|
|
|
|
Murano applications have a separate logging handler and a separate file where
|
|
all logs from application definitions should be provided. Open the
|
|
:file:`logging.conf` file and check the ``args: ('applications.log',)``
|
|
option in the ``handler_applications`` section.
|
|
|
|
Verify that ``log_config_append`` is not empty and set to the
|
|
:file:`logging.conf` location.
|
|
|
|
Issues during configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If any issues occur, first of all verify the following:
|
|
|
|
* All murano components have consistent versions: murano-dashboard and
|
|
murano-engine should use the same or compatible python-muranoclient version.
|
|
Dependent component versions can be found in :file:`requirements.txt` file.
|
|
|
|
* The database is synced with code by running:
|
|
|
|
.. code-block:: console
|
|
|
|
murano-db-manage --config-file murano.conf upgrade
|
|
|
|
**Failed to execute `murano-db-manage`**
|
|
|
|
* Make sure the ``--config-file`` option is provided.
|
|
* Check `connection` parameter in the provided configuration file. It should
|
|
be a `connection string <http://docs.sqlalchemy.org/en/rel_0_8/core/engines.html>`_.
|
|
|
|
* Check that MySQL or PostgreSQL (depending of what you provided in the
|
|
connection string) Python modules are installed on the system.
|
|
|
|
**Applications panel is not seen in horizon**
|
|
|
|
* Make sure that the following files are copied to the
|
|
``openstack_dashboard/local/enabled`` directory, and _50_murano.py is copied
|
|
to ``openstack_dashboard/local/local_settings.d`` directory.
|
|
|
|
* _50_dashboard_catalog.py
|
|
* _51_muranodashboard.py
|
|
* _60_panel_group_browse.py
|
|
* _63_panel_murano_catalog.py
|
|
* _70_panel_group_manage.py
|
|
* _71_panel_murano_packages.py
|
|
* _72_panel_murano_images.py
|
|
* _73_panel_murano_categories.py
|
|
* _80_panel_group_applications.py
|
|
* _81_panel_applications_environments.py
|
|
|
|
* Check that murano data is not inserted twice in the settings file and as a
|
|
plugin.
|
|
|
|
**Applications panel can be browsed, but 'Unable to communicate to murano-api server.' appears**
|
|
|
|
If you have murano registered in keystone, verify the endpoint URL is valid
|
|
and service has *application-catalog* name. If you do not want to register the
|
|
murano service in keystone, just add ``MURANO_API_URL`` option to the horizon
|
|
local setting.
|
|
|
|
Issues during deployment
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Besides identifying errors from log files, there is another and more flexible
|
|
way to browse deployment errors -- directly from UI. When the *Deploy Failed*
|
|
status appears, navigate to :menuselection:`Environment Components` and click
|
|
the :guilabel:`Latest Deployment Log` tab. You can see steps of the deployment
|
|
and the one that failed would have red color.
|
|
|
|
**while scanning a simple key in "<string>", line 32, column 3: ...**
|
|
|
|
There is an error in the YAML file format. Before uploading a package,
|
|
validate your file in an online YAML validator like
|
|
`YAMLint <http://www.yamllint.com/>`_.
|
|
Later `validation tool <https://blueprints.launchpad.net/murano/+spec/murano-package-verification-tool>`_
|
|
to check package closely while uploading will be added.
|
|
|
|
**NoPackageForClassFound: Package for class io.murano.Environment is not found**
|
|
|
|
Verify that murano core package is uploaded. If not, the content of the
|
|
``meta/io.murano`` folder should be zipped and uploaded to Murano.
|
|
|
|
**[keystoneclient.exceptions.AuthorizationFailure]:**
|
|
**Authorization failed: You are not authorized to perform the requested action. (HTTP 403)**
|
|
|
|
The token expires during the deployment. Usually the default standard token
|
|
lifetime is one hour. The error occurs frequently as, in most cases, a
|
|
deployment takes longer than that or does not start right after a token is
|
|
generated.
|
|
|
|
Workarounds:
|
|
|
|
* Use trusts. Only possible in the v3 version. Read more in the
|
|
`official documentation <https://wiki.openstack.org/wiki/Keystone/Trusts>`_
|
|
or `here <https://docs.openstack.org/heat/latest/admin/auth-model.html>`_.
|
|
Do not forget to check the corresponding heat and murano settings. Trusts
|
|
are enabled by default in murano and heat since Kilo release.
|
|
|
|
In murano, the corresponding configuration option is located in the
|
|
``engine`` section:
|
|
|
|
.. code-block:: ini
|
|
|
|
[engine]
|
|
|
|
...
|
|
|
|
# Create resources using trust token rather than user's token (boolean
|
|
# value)
|
|
use_trusts = true
|
|
|
|
If your Keystone runs v2 version, see the solutions below.
|
|
|
|
* Make logout/login to compose a new token and start the deployment again.
|
|
Would not help for long deployment or if the token lifetime is too small.
|
|
|
|
* Increase the token lifetime in the keystone configuration file.
|
|
|
|
**The murano-agent did not respond within 3600 seconds**
|
|
|
|
* Check transport access to the virtual machine: verify that the router has a
|
|
gateway.
|
|
* Check the RabbitMQ settings: verify that the agent has valid RabbitMQ
|
|
parameters.
|
|
Go to the spawned virtual machine and open :file:`*/etc/murano/agent.conf`
|
|
on the Linux-based machine or :file:`C:\\Murano\\Agent\\agent.conf` on the
|
|
Windows-based machine. Additionally, you can examine agent logs that by
|
|
default are located at :file:`/var/log/murano-agent.log` The first part of
|
|
the log file contains reconnection attempts to the RabbitMQ since the valid
|
|
RabbitMQ address and queue have not been obtained yet.
|
|
* Verify that the ``driver`` option in ``[oslo_messaging_notifications]`` group
|
|
is set to ``messagingv2``.
|
|
|
|
**murano.engine.system.agent.AgentException**
|
|
|
|
The agent started the execution plan but something went wrong. Examine agent
|
|
logs (see the previous paragraph for the logs placement information). Also,
|
|
try to manually execute the application scripts.
|
|
|
|
**[exceptions.EnvironmentError]: Unexpected stack state NOT_FOUND or UPDATE_FAILED**
|
|
|
|
An issue with heat stack creation, examine the heat log file. Try to manually
|
|
spawn the instance. If the reason of the stack creation fail is ``no valid
|
|
host was found``, there might be not enough resources or something is wrong
|
|
with the nova-scheduler.
|
|
|
|
**Router could not be created, no external network found**
|
|
|
|
Find the ``external_network`` parameter in the ``networking`` section of the
|
|
murano configuration file and verify that the specified external network does
|
|
exist through Web UI or by executing the
|
|
:command:`openstack network list --external` command.
|
|
|
|
**Deployment log in the UI contains incomplete reports**
|
|
|
|
Sometimes logs contain only two messages after the application deployment.
|
|
There are no messages provided in applications themselves:
|
|
|
|
.. code-block:: console
|
|
|
|
2015-09-21 11:14:58 — Action deploy is scheduled
|
|
2015-09-21 11:16:43 — Deployment finished successfully
|
|
|
|
To fix the issue, set the ``driver`` option in the :file:`murano.config` file
|
|
to ``messagingv2``.
