Hi, Thank you for the report Ivandro, and suggestion from Ghanshyam. I'd like to reply about asking an image installed Tacker. Unfortunately, we don't have such an image currently. If you still have any problem after following Ghanshyam's suggestion, I'd like to support for your installation, and update documentation if required.

Hello Mr. Yasufumi,

Sorry for later replay. I will be replaying to your feedback timely.

hope to have your support and if possible, guide on how to troubleshooting.

here are my scenario:

I want to install tacker project using the following guide: https://docs.openstack.org/tacker/train/install/devstack.html

Hi Folks,

I do wonder how Blazar became part of Tacker discussion.

It is because local.conf suggested in https://docs.openstack.org/tacker/train/install/devstack.html enables blazar devstack plugin. Back to the original query, it is caused by the inconsistent branch usage. The cause of the problem asked looks like that local.conf fetches the master branch of devstack plugins but stable/train devstack is used. The default value of USE_PYTHON3 is False in DevStack stable/train, so python 2.7 is used, but DevStack plugins from the master branch is used, so modules with python3 support only are being installed into python 2.7 environment. What I can say now are: - If you use the stable/train branch, specify stable/train for devstack plugins in local.conf instead of the master branch if you use the stable/train branch. - If you use the master branch, checkout the master branch of DevStack instead of stable/train. -amotoki

As for Tacker image, Kolla has working Tacker images [1] [2] (also available with other distros), also in Kolla-Ansible [3], ready for deployment. :-)

Hello Mr. Ghanshyam, Appreciate your quickly replay. Regarding your comments: *"p**ython-blazarclient (even all OpenStack services and lib except swift and Storlets) are now **python3-only means their latest version _will not be installed on <py3.6 env_.*" it means that I should use python 3.0 and not 3.6? I prefer to use python 3. Following the instruction on manual (updated ubuntu server and start the installation) automatically selected python 2.7 which was default on ubuntu. I think I will remove version 2.7 and install 3.0, then start a new installation. thank you very much for your support!!! BR On 4/23/2020 2:54 AM, Ghanshyam Mann wrote:

Hello Mr. Hyunik,

I try to run a new installation using the local.conf file that you suggest and the installation was not successful. here are additional information about my setup:

- new installation and update ubuntu 18.04.4;

- on vmware workstation, 8Gb RAM, 100G SSD HD, 4 vCPU;

- local file and logs in attachment.

- I used the same steps as described below (add user, download devstack, start the installation, ...)

- before the installation, only the python3.6 was installed:

Hi. lvandro.

I think you have a problem with os.

Yesterday, I checked the master version of tacker using devstack. And It installed well.

I used ubuntu 18.04 and used the master version devstack.

I attached my local conf option like below. Please check it .

If you have any questions, feel free to contact me and tacker ML.

Sorry for later replay. I will be replaying to your feedback timely.

hope to have your support and if possible, guide on how to troubleshooting.

here are my scenario:

I want to install tacker project using the following guide: https://docs.openstack.org/tacker/train/install/devstack.html

I am not sure What kind of error you got, but, according to your error, it is just a timeout error. After you get the error message, You can check kubernetes component status. if it is not working properly, we should find a reason. 2020년 4월 23일 (목) 오후 11:15, Ivandro <i201822117@hust.edu.cn>님이 작성:

Hello Mr. Hyunik,

I try to run a new installation using the local.conf file that you suggest and the installation was not successful. here are additional information about my setup:

- new installation and update ubuntu 18.04.4;

- I used the same steps as described below (add user, download devstack, start the installation, ...)
