[Ussuri] [Zun] Container deployment problem with Zun "There are not enough hosts available"
Hello,
I have an Openstack cluster, with basic services and functionality working based on ussuri release.
I am trying to install the Zun service to be able to deploy containers, following
[controller] -- https://docs.openstack.org/zun/ussuri/install/controller-install.html and [compute] -- https://docs.openstack.org/zun/ussuri/install/compute-install.html
I used the git branch based on ussuri for all components.
I veryfined kuryr-libnetwork operation issuing from the compute node # docker network create --driver kuryr --ipam-driver kuryr --subnet 10.10.0.0/16 --gateway=10.10.0.1 test_net
and seeing the network created successfully, etc.
I am not very sure about the zun.conf file. What is the "endpoint_type = internalURL" parameter? Do I need to change internalURL?
From sudo systemctl status zun-compute i see:

What is this problem? any advice? I used the default configuration values ([keystone_auth] and [keystone_authtoken]) values based on the configuration from the above links.

seems to work fine.
However when i issue e.g., openstack appcontainer run --name container --net network=$NET_ID cirros ping 8.8.8.8
i get the error: | status_reason | There are not enough hosts available.
Any ideas?
One final thing is that I did see in the Horizon dashboard the container tab, to be able to deploy containers from horizon. Is there an extra configuration for this?
sorry for the long mail.

Hi,
It looks zun-compute wants to create a resource provider in placement, but placement return a 409 response. I would suggest you to check placement's logs. My best guess is the resource provider with the same name is already created so placement returned 409. If this is a case, simply remove those resources and restart zun-compute service should resolve the problem.
Best regards, Hongbin

Hello,
you are right, that fixed the problem.
In order to solve the problem i revisited https://docs.openstack.org/placement/ussuri/install/verify.html I executed: openstack resource provider list Then removed the host that i use for containers, restarted the zun-compute at the host and works perfectly. Thank you very much for your input.
One more thing, I don't see at the horizon dashboard the tab for the containers (i just see the nova compute related tab). Is there any additional configuration for this?
btw, from https://docs.openstack.org/placement/ussuri/install/verify.html, i used pip3 install osc-placement (instead of pip install..)
all the best Pavlos.

seems to work fine.
However when i issue e.g., openstack appcontainer run --name container --net network=$NET_ID cirros ping 8.8.8.8
i get the error: | status_reason | There are not enough hosts available.
Any ideas?
One final thing is that I did see in the Horizon dashboard the container tab, to be able to deploy containers from horizon. Is there an extra configuration for this?
sorry for the long mail.

Sorry for late reply. I missed this email.
This is the Zun UI installation guide: https://docs.openstack.org/zun-ui/latest/install/index.html#manual-installat... . About your suggest of pip3 installation, I will add a note to clarify that. Thanks for pointing it out.
Best regards, Hongbin

In order to solve the problem i revisited https://docs.openstack.org/placement/ussuri/install/verify.html I executed: openstack resource provider list Then removed the host that i use for containers, restarted the zun-compute at the host and works perfectly.
Thank you very much for your input.
One more thing, I don't see at the horizon dashboard the tab for the containers (i just see the nova compute related tab). Is there any additional configuration for this?
btw, from https://docs.openstack.org/placement/ussuri/install/verify.html, i used pip3 install osc-placement (instead of pip install..)

Hi,
It looks zun-compute wants to create a resource provider in placement, but placement return a 409 response. I would suggest you to check placement's logs. My best guess is the resource provider with the same name is already created so placement returned 409. If this is a case, simply remove those resources and restart zun-compute service should resolve the problem.

Hello,
no worries, million thanks for the support and the link for the UI.
One more thing to point out is that in ( https://docs.openstack.org/zun/xena/install/compute-install.html) at step 9, the curl command is fixed to amd64 architecture --since i have an aarch64 system i fetched the appropriate version from https://github.com/containernetworking/plugins/releases/, and worked fine.
best, Pavlos.

and seeing the network created successfully, etc.
I am not very sure about the zun.conf file. What is the "endpoint_type = internalURL" parameter? Do I need to change internalURL?

What is this problem? any advice? I used the default configuration values ([keystone_auth] and [keystone_authtoken]) values based on the configuration from the above links.

seems to work fine.
However when i issue e.g., openstack appcontainer run --name container --net network=$NET_ID cirros ping 8.8.8.8
i get the error: | status_reason | There are not enough hosts available.
Any ideas?
One final thing is that I did see in the Horizon dashboard the container tab, to be able to deploy containers from horizon. Is there an extra configuration for this?
sorry for the long mail.
best, Pavlos
