Single Instance OpenStack IP Network Configuration

由 拈花ヽ惹草 提交于 2021-02-08 12:10:57
问题 Am curious about how OpenStack handles IP configuration, i have a complete working openstack dashboard with a static IP of 192.168.1.73/24 and i want to change it to something else. Running as a VM using RHEL\Scientific Linux\Centos 7.5 as the Guest Host. Am running openstack-queens (repo) -- /etc/yum.repos.d What i've tried and failed... 1.Changing static IP in /etc/sysconfig/network-scripts/ifcfg-eth0 2.Made sure in /etc/resolv.conf reflects my new configuration. 2.Replacing IP

DevStack instances can't be reached outside devstack node

由 99封情书 提交于 2020-02-28 01:38:21
问题 Following official documentation, I'm trying to deploy a Devstack on an Ubuntu 18.04 Server OS on a virtual machine. The devstack node has only one network card (ens160) connected to a network with the following CIDR 10.20.30.40/24 . I need my instances accessible publicly on this network (from 10.20.30.240 to 10.20.30.250). So again the following the official floating-IP documentation I managed to form this local.conf file: [[local|localrc]] ADMIN_PASSWORD=secret DATABASE_PASSWORD=$ADMIN

How to check number of floating IPs available in a pool?

由 两盒软妹~` 提交于 2019-12-13 07:29:42
问题 I am writing a script to create a VM on Openstack. I may get error if floating IPs get exhausted in pool. How can I check if there are floating IPs available in that pool or not? Is there a way where openstack can automatically choose the pool from all available pools? 回答1: You have a choice of working from the API (using curl, for example) or using the openstack CLI, which is what you were using when you submitted this question. The CLI is easier for straight scripting. Here is how you query

how to assign network to vm using jclouds in openstack and How to list all networks in Openstack using Jclouds

问题 Can someone help me understanding how to assign a specific network to a newly created VM using the JClouds API in OpenStack? I'm using following code to create the real server: CreateServerOptions[] serverOptions = new CreateServerOptions[0]; ServerCreated serverCreated = serverApi.create(clonedVmName, imageId, FlavourId, serverOptions); Also I'm using v1.0-quantum APIs to fetch all the networks as follows but it's not returning any. I'm not sure what's wrong with the following code: Iterable
