Cloud computing competition -- basic part of 2020 competition [task 3]
2022-04-23 09:21:00 【King_ nul】
Preface
It's been nearly two years , Just recently closed home , When I was free, I did the questions of the previous competition , Learning and doing , Don't do it again , I'll soon forget all the things I've learned before .
Welcome to my blog
Before doing the problem , Be sure to build all the platforms, and then start to do it after there is no problem , Otherwise, when there are problems later , It takes a lot of time to solve , The task ahead Is to build the basic environment .
2020 Cloud computing Events ( National Basic Edition ) Title address
Task three – Opensatck Operation and maintenance tasks
Topic 1 ： Image management
stay openstack On the private cloud platform , Use / The attachment / Private cloud attachments / Under the cirros-0.3.4-x86_64-disk.img Mirror image , Use the command to create a file named cirros Mirror image . Submit the user name of the control node after completion 、 Passwords and IP Address to answer box .( The examination environment will provide the required images and other materials )
# Because I'm not ready here Mirror image Download an image directly online , The examination environment cannot be downloaded online , You can download it and use it first
[root@controller opt]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
# If you make a mistake -bash: wget: command not found Just use yum -y install wget Install it. wget
[root@controller opt]# ls
centos cirros-0.4.0-x86_64-disk.img OpenStack
# source once admin-openrc file
[root@controller opt]# source /etc/keystone/admin-openrc.sh
# Take a look at the existing image , Avoid image name conflicts
[root@controller opt]# glance image-list

Topic two ：heat Template Management
stay openstack On the private cloud platform , stay /root Write templates under the directory server.yaml, Create a “m1.flavor”、 ID by 1234、 Memory is 1024MB、 Hard disk is 20GB、vcpu The number of 1 Type of virtual machine . Submit the user name of the control node after completion 、 Passwords and IP Address to answer box .（ Please be prepared before submitting information yaml The environment in which the template is executed ）
heat yes Openstack An automated orchestration component in , For batch creation of resources and networks , You can also build relationships between resources .
Basic concepts ：
– Stack （stack）： A collection of management resources . A collection of instantiated resources defined in a single template , yes Heat Manage the logical units of the application , Often corresponds to an application .
– Templates （template）： How to use code to define and describe the stack . Describes all component resources and the relationship between component resources , yes Heat At the heart of .
– resources （resource）： Objects that will be created or modified during orchestration . Resources can be networks 、 Router 、 subnet 、 example 、 volume 、 float IP、 Security team, etc .
– Parameters （parameters）：heat Top level in the template key, Define when creating or updating stack What data can be passed to customize the template .
– Parameter group （parameter_groups）： Used to specify how input parameters are grouped , And the order in which the parameters are provided .
– Output （outputs）：heat Top level in the template key, After definition instantiation stack Data to be returned .

Topic three ：swift Fragmentation storage
Use openstack Private cloud platform , Its installation Swift service , New name is chinaskill The container of , take cirros-0.3.4-x86_64-disk.img Upload the image to chinaskill In the container , It shall be stored in sections , The size of each segment is 10M. Submit the user name of the control node after completion 、 Passwords and IP Address to answer box .
