Agreed.

Every new features should be introduced in a backward-compatible way if possible. If new change will break existing version, it should be properly versioned and/or follow the corresponding deprecation process. Please feel free to ask for clarification if the procedure is unclear.

Best regards,

Thanks Hongbin for your info.

I really think it is not good way for new feature introduced.
As new feature introduced often break old work. it more often better with add-in feature is plus, old work still funciton.

Or at least, the error should say "swarm bay now requires trust to work, please use trust related access information before deploy a new swarm bay"



Thanks

Hi team,

FYI, you might encounter the following error if you pull from master recently:

magnum bay-create --name swarmbay --baymodel swarmbaymodel --node-count 1
Create for bay swarmbay failed: Failed to create trustee %(username) in domain $(domain_id) (HTTP 500)"

This is due to a recent commit that added support for trust. In case you don’t know, this error can be resolved by running the following steps:

# 1. create the necessary domain and user:
export OS_TOKEN=password
export OS_URL=http://127.0.0.1:5000/v3
export OS_IDENTITY_API_VERSION=3
openstack domain create magnum
openstack user create trustee_domain_admin --password=secret --domain=magnum
openstack role add --user=trustee_domain_admin --domain=magnum admin

# 2. populate configs
source /opt/stack/devstack/functions
export MAGNUM_CONF=/etc/magnum/magnum.conf
iniset $MAGNUM_CONF trust trustee_domain_id $(openstack domain show magnum | awk '/ id /{print $4}')
iniset $MAGNUM_CONF trust trustee_domain_admin_id $(openstack user show trustee_domain_admin | awk '/ id /{print $4}')
iniset $MAGNUM_CONF trust trustee_domain_admin_password secret

# 3. screen -r stack, and restart m-api and m-cond
