Ansible Tower implements a role based access control system. It may appear that you can edit objects that do not belong to you–like being able to pull up an edit dialog of your teammates, which you have been granted permission to view–but when you try to edit something, you will receive a 403 error and you cannot view any information you should not already have access to as defined in the system.
When Tower is accessed via hostname only (e.g. https://my-little-tower), trying to read the SAML metadata from /sso/metadata/saml/ generates a
sp_acs_url_invalid server error.
A configuration in which uses SAML when accessing Tower via hostname only instead of an FQDN, is not supported. Doing so will generate an error that is captured in the tower.log file and in the browser with full traceback information.
At this time, Tower does not support running when the operating system is configured to operate in FIPS mode.
When performing a host comparison against a single host, if there is only one (1) run for the selected date, Tower may display a message saying it could not find any scan job runs in one of the columns.
Live events status dots are either seen as a red or orange dot at the top of the Tower Dashboard when something goes wrong. They are not seen at all when the system is in a healthy state. If you encounter a red or orange live events status indicator, even when your system seems fine, the following suggestions may offer a solution:
https://tower-ip:8080/, which should allow you to accept the certificate for the machine.
Live event status dots are used for troubleshooting problems with your Tower instance and the
socketio logs can point out anything problematic. You can collect troubleshooting help by running a
sosreport. As root, run the command
sosreport from your system to automatically generate a diagnostic tar file, then contact Ansible’s Support team with the collected information for further assistance.
Starting with Ansible Tower 2.2.0, live events status indicators only appear if Tower detects a problem. In earlier releases, a green status dot was shown to indicate a healthy system.
When using a custom SSL certificate with Live Events, you must:
If a custom location or encrypted keyfile is used, the Live Events service will not function properly.
If you are using a certificate chain, you must concat the chain file to
tower.cert and point the
SSLCertificateChainFile parameter in
If you have a vmware instance that uses a self-signed certificate, then you will need to add the followig to the Source Vars configuration of the Cloud Group:
"source_vars": "---\nvalidate_certs: False",
If celery is not cleanly shutdown, it leaves a
/var/lib/awx/beat.db file on disk.
If you observe the traceback in the initial comment, you must manually delete the
/var/lib/awx/beat.db file and restart Tower.
The following connection error displays in Tower:
This error is the result of Safari silently refusing to establish a connection to a web socket that is using a self-signed certificate. To resolve this issue, you must set Safari to always trust the website upon first visiting it:
If you click Continue without checking the checkbox, this error will persist.
Instances have been reported that
su commands do not work when using an entirely local playbook or a playbook with some local_actions cases. This is likely due to PRoot being enabled. To use
su commands with local playbooks or those with local_actions, PRoot must be disabled. You can disable PRoot by navigating to the
/etc/tower/settings.py file, setting
AWX_PROOT_ENABLED=False, then restarting services with the
ansible-tower-service restart command.
During the testing of Ansible Tower 2.3.0, it was discovered that the installation program does not handle the option to enable
su command support.
When using the Tower installation program to install Tower to a remote system where
su access is required, the installation program will not work. To workaround this issue, you should manually run the
ansible-playbook command with the
The PRoot functionality in Ansible Tower limits which directories on the Tower file system are available for playbooks to see and use during playbook runs. If you are attempting to customize SSH behavior by using a custom SSH configuration in the Tower user’s home directory, this directory must be added to the list of directories exposed by PRoot.
For example, to add a custom SSH config in
/var/lib/awx/.ssh/config and make it available for Tower jobs, edit the
/etc/tower/settings.py file and add that path to the
AWX_PROOT_SHOW_PATHS = [ '/var/lib/awx/.ssh/' ]
Once the paths you need have been added to
settings.py, restart Tower using the admin utility script,
If you are using the bundled installer for Ansible Tower 2.3.0, note that only Red Hat Enterprise Linux and CentOS are supported at this time. Ubuntu support has not yet been added to the bundled installer. Ubuntu users can continue to use the unbundled installer.
Proactive session limits will kick the user out when the session is idle. It is strongly recommended that you do not set the session limit to anything less than 1 minute, as doing so will break your Ansible Tower instance.
Ansible 2.0 introduces strategies, such as
strategy: free, but Ansible Tower support for these new strategies is not yet available in Tower version 2.4.0. This Ansible feature will not be added to Tower until a later release.
If you attempt to use
strategy: free in Ansible Tower, jobs will run, but they will not display properly in the Job Detail page.
Refer to the following link for more information: https://docs.ansible.com/ansible/playbooks_strategies.html
Once a user who logs in using social authentication has been deleted, the user will not be able to login again or be recreated until the system administrator runs a
cleanup_deleted action with
days=0 to allow users to login again. Once
cleanup_deleted has been run, Tower must be restarted using the
ansible-tower-service restart command. Accounts which have been deleted prior to having the
cleanup_deleted action run will receive a “Your account is inactive” message upon trying to login.
If your Tower server has a version of OpenSSH that predates 5.7, jobs will fail when launched jobs with ECDSA credentials.
If the key is unencrypted, your job will fail with a message similar to:
Enter passphrase for /tmp/ansible_tower_RcQweY/tmph9Jote:
If the key is encrypted and you have entered the correct passphrase, your job will fail with:
Enter passphrase for /tmp/ansible_tower_nYW0SO/tmpgJSimD: Bad passphrase, try again for /tmp/ansible_tower_nYW0SO/tmpgJSimD:
If ECDSA credentials are not working for your use, you could try using ED25519 keys instead.
