 Hi everyone. I'm sorry. I'm an H and Yeah, I Don't know your excuse. All right So I'm here to do Presenting for my other colleague and one one from the intro So because they are cannot be here due to the visa problem And if you on the case here, I will show you a one One one case for for color Here I want to talk about some this this Content background why we are using color and how we use color and cause future cause all team We are we I'm from 99 cloud and they enter and then I called in the intro have some guys Working on corner projects Here's the background the big data and and the cloud are two are to very popular at the popular industry field at Country in China in the China IT field so when the intro teams are Working not in on the big data, but but you know that big data are very very infrastructure infrastructure dependent, so they are they are also very require one new reliable and one One one as your infrastructure management feature to to support their big data development so they are So they are meeting the big data and the cloud the interest ST ST all teams are focused on developer big data service solutions and then they are they are also Contributed to open open source project like over stack. I think in the color and in the some some projects and they are also working on so they are because they are They are also they are also very active on big data projects such as bark and the hard dope and And the folks on cloud performance tuning the big data is the big data needs performance So they also collaborate with the global SVs the 99 cloud is is a partner network with What along with the intro? so since we are development team we are We are facing many Many problems or many many we have many requirements So such as we are since we are doing software development. We are We require to do some version control some agile development deployment and maybe we need a hardware maintenance and also we needed to quick deploy deploy our our development environment so that is We have very We are eager to have a very agile infrastructure management sequence I think the motivations folks motivations and Why we use the over stack color Over stack over stack Provides multi tennis multi tennis features you know we We just like we are we are development teams and and And every do I'm kids and user and as nature to environment so that is very very good choice to to the to support the mother Terence and and and On the other side the dog have us to cover also the dependency issues by using control technologies Before the caller we also have some pop it or save technology to do the over stack deployment but But the net deploy deploy the over stack components are bigger together. So they are not easy to to do some Individual component to upgrade or some Do some as nations so this is Call I have us to do some to the lease to to use the container to to SNH one component to another components also In a corner we can also we can also use it to do the maintenance and the upgrade Sometimes when we are doing our Doing our development we found that and there are some bug on the current version of some over stack components How to do upgrade this this individual components? Yes, we We use the call we use we use the container and the caller to to do the individual component of gracious so this is the interest use guys on the keynote to do some so to have To have this one it deals the complexity This is a caller's containers feature and the easier deployment the caller is very To use caller we can very easy to deployment on-demand over stack seasons rolling upgrade I have said that In a call in across the container technologies We can very easy to upgrade to upgrade to an individual component of this over stack season this is our This is our this is the development never environment by our by our team Here we have three reports or three ports of the servers on the left is the open stack count on the open stack count we also We have some normal of normal computer to to to to deploy some some some ITC chance and and in the middle is the self we have We have a big set of self self storage systems and the over stack over stack we use the we use the same to To to use the self see self storage systems also we On the on the right side that we have some bare matter bare matter machines the bare matter machines somewhere We also sometimes we are using the self self storage seasons Well, it is It is we also use an over stack to to bootstrap our bare matter seasons and now there is the some other Some other components are on the networks and the management of records private private networks and and And and on the northbound is the public network Okay to use corner ansible for almost that solution is very it can be concluded into these eight steps First of you first on the corner ansible deployment system. We have one deployment server on a depend server We will have a darker ansible almost that client libraries and TP server Installations and also on a deployment service we we will have to we will We will need to access the man Manage the nodes while Possible the last SSH so this knows must be registered in the local Lane servers We can use the simple to add it to the ATC host file To do the name server resolution This is the for an isn't pretty comments on development server and the step two is to Is to do some do to do some Preventer on the manager's nose One one recommend is just the the docker. We have a we need a docker running on the manage manage nodes And the step two is download the docker open stack images on that deployment server and the steps for is to is to Set up a docker local registry and the node node each of the download the images and And and and the step five is to add each multi-node file or inventory. In fact, you can then this file By by any what you want To specify the one knows are talk. Well, what knows are taking water roles such as the not the one is taking No, our computer. No two is taking network neutral network roles such as And the step six is to edit a global three young file To specify or to configure to be installed all the staggered features Yes In all the second there are many components and in the global in the globe's young file We can specify the water components are enabled and how to store it but it is very simple and And in in step seven we can use we can use the call the answer book command line such as call the answer book pre checks to check in the syntax or the semantics often is okay the time up and Start to deploy is that is depth age and then there are some there are some There's some features like here where I want to talk about and the group of groups of XML file we can enable HL or settings and and also we can use the external safe and safe she turns This is the usage as I want to talk We are we have met during the installation. This is the Maria DB's programs and second to his upgrade issues and Also, we have we have we have considered that downgrow the issues downgrade the issues Yeah, if we if we run call the ends of upgrade failed how to How to do that downgrade? This is the cause of future plan new features in Ocata We made Ocata stable and the support more of stack projects Yeah, and the future plans cause Kubernetes support That that color we have a color ansible. We also have a corner K Kubernetes We also need to do the multi regions Okay, after that we can enjoy our life That's a very simple case study show. I think that ties up
