[murano] Galera Table package_to_tag has no PRIMARY_KEY


Hi Rong,

 

thank you for your answer!

 

I will test it with changing the pxc_strict_mode.

 

But in your second link I can read that it would be better to add a PRIMARY_KEY to the table?

 

Best regards,

 

Marc

Hi Marc,

 

 

Glad to hear you are using murano.

I googled this, the reason is Percona using pxc_strict_mode = ENFORCING will catch error when table without primary keys. package_to_tag table don't have a primary key. I think you can set the mode Permissive.

Hello,

 

uploading an application to Murano fails after upgrading "percona-xtradb-cluster-common-5.6" to "percona-xtradb-cluster-common-5.7":

 

Importing package io.murano

Error {"explanation": "The server has either erred or is incapable of performing the requested operation.", "code": 500, "error": {"message": "(pymysql.err.InternalError) (1105, u'Percona-XtraDB-Cluster prohibits use of DML command on a table (murano.package_to_tag) without an explicit primary key with pxc_strict_mode = ENFORCING or MASTER') [SQL: u'INSERT INTO package_to_tag (package_id, tag_id) VALUES (%(package_id)s, %(tag_id)s)'] [parameters: {'package_id': 'a345ab1fe4924aaf8ed32f954a6fe32d', 'tag_id': '0cb3765d7fe1486ba9741f4eb9b2a437'}]", "traceback": null, "type": "DBError"}, "title": "Internal Server Error"} (HTTP 500) occurred while installing package io.murano

 

If i looks on the galera table, i get the following information:

 

$ mysql -u murano -p

 

mysql> Use murano;

Murano is installed in the latest version of queens (https://github.com/openstack/murano/tree/stable/queens).

 

Has anyone an idea?
