Request limit exceeded: JSON body size (2299844 bytes) exceeds maximum allowed size (2097152 bytes).

[Yossi Ovadia]

Deployment of RDO Queens with containers on 9 servers (3 controller, 3 storage , 3 computes ) fails with the following err-

Error validating environment for plan overcloud: ERROR: Request limit exceeded: JSON body size (2299844 bytes) exceeds maximum allowed size (2097152 bytes).

Log - http://paste.openstack.org/show/687788/

The resolved bug - https://bugs.launchpad.net/tripleo/+bug/1667697 , Changed the value to 2097152 which apparently is not enough.

Changing the value of max_json_body_size to number higher than 2299844 and restarting httpd resolved the problem.

Now the question is to what value we want to change the default ?

    Increase size of Heat max_template_size

    Most of the HTTP servers default max body size to 1MB, Apache, Nginx.
    That default value is ok as long as users mostly get data from server
    but when something needs to be uploaded, 1MB limit is often not enough.
    This is what we see with Heat and some of the large templates.
    It's not uncommon that WSGI apps have 10MB+ body size limit,
    so with the current Heat default value we are still in low range sizes.

    Original Heat 'max_template_size' default value was 1M.
    In instack-undercloud we bumped it to 2M, bug #1667697.
    This change increases it to 4MB.
