Hi!

I'm new in ansible, and I try to install a galera cluster on my test enviroment. But I have this error:

Traceback (most recent call last): File "/usr/local/Cellar/ansible/6.1.0/libexec/lib/python3.10/site-packages/ansible/template/init.py", line 1096, in do_template res = self.environment.concat(rf) File "/usr/local/Cellar/ansible/6.1.0/libexec/lib/python3.10/site-packages/ansible/template/native_helpers.py", line 70, in ansible_eval_concat head = list(islice(nodes, 2)) File "

I tried to find out what was the problem, but I wont find this variable anywhere.

Ansible version: ansible [core 2.13.1] config file = None configured module search path = ['/Users/imagyar/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/local/Cellar/ansible/6.1.0/libexec/lib/python3.10/site-packages/ansible ansible collection location = /Users/imagyar/.ansible/collections:/usr/share/ansible/collections executable location = /usr/local/bin/ansible python version = 3.10.5 (main, Jun 23 2022, 17:15:25) [Clang 13.1.6 (clang-1316.0.21.2.5)] jinja version = 3.1.2 libyaml = True

playbook.yml:

• name: Example Playbook hosts: all tasks:
  • name: Include ansible-mariadb-galera-cluster include_role: name: mrlesmithjr.mariadb_galera_cluster

Thanks!

Hello @zaraquer,

You need to overwrite the value from defaults named galera_cluster_nodes_group and use there the actual name of the group where the galera cluster should be installed.

My galera cluster override file is something along these lines:

---
galera_cluster_bind_interface: 'eth0'  # make sure this interface exists in your servers
# yamllint disable-line rule:line-length
galera_cluster_name: 'clients_mariadb_gc_staging'  # this name should be under 32 chars or galera cluster will not start
galera_cluster_nodes_group: 'clients_mariadb_galera_cluster'  ## this is the most important one
mariadb_version: '10.6'
mariadb_mysql_root_password: "some-password"

Hi @eRadical !

Thanks for your comment! I already named it after the group name in my inventory file.

Define the name of the cluster

galera_cluster_name: "galera-test"

Define Ansible group in which the nodes exist to be part of the cluster

galera_cluster_nodes_group: "mariadb"

Inventory file: [mariadb] mariadb1 ansible_host=xxx.xxx.xxx.51 mariadb2 ansible_host=xxx.xxx.xxx.52 mariadb3 ansible_host=xxx.xxx.xxx.53

[all:vars] ansible_python_interpreter=/usr/bin/python3

@zaraquer - any progress on this?

Can you paste a file with ansible-playbook ran with "-vvvv" ?

Hi!

I figured out, there was a missing quote in the main.yml and needed to change some values. It seems it solved now.

Glad you sorted it out.
