Docker – Implementation => Docker Install




How to used docker without installing to our machine?

To run docker resurse can be not enough in our machine, so then go to this site play with docker for that..

URL :

https://labs.play-with-docker.com/

 

Docker containers are originally run on LINUX OS. Later Docker made its platform available for other operation systems. But simple limitation. Limit - Docker was running inside LINUX based virtual machine on top of the operating system. So Docker can run in multiple OS, but still LINUX is the middle man. But recently release Docker can run now natively on the windows. Linux support is not needed and Docker container run on windows kernel itself.

To run Docker on windows you need,

64 bit windows 10(pro,Edu,Stu), Enable hyper-V,  Enable virtualization.

IF you want to run Docker on older version on windows, you need Docker tool for that. Docker needs type one hypervisor in windows it is hyper-V. Hyper-V is a lightweight virtualization solution build on top of the hypervisor framework, so you don’t not need to virtual box and just want to enable hypervisor and virtualization.

 

01. For WINDOWS

Note: Hyper–V should be enabled in windows.

https://hub.docker.com/editions/community/docker-ce-desktop-windows/

Go to above URL and download and install the docker.

 

Verify docker is installed or not

In the CMD

01. docker -version

 

 

 

Test Docker with run hello world

02. docker run hello-world

03. See image => docker images

04. See running container => docker container ls

05. See container status => docker ps -a

 

02. For LINUX – UBUNTU

I am installing Docker on Ubuntu 18.04 but bellow guide is valid with other versions also.

There are multiple ways which we can install Docker on Ubuntu (like: package way,script way,repository way etc.).Go and see....

https://docs.docker.com/engine/install/ubuntu/

 

 

I am using : Install using the convenience script

Uninstall older version

In the terminal

01. $ sudo apt-get remove docker docker-engine docker.io containerd runc

Install using the convenience script

 

02. $ curl -fsSL https://get.docker.com -o get-docker.sh

03. $ sudo sh get-docker.sh

If you would like to use docker as non-root user, you should now consider adding your user to the "docker" group with somthing like:

04. sudo usermod -aG docker your_pc_name   

   sudo usermod -aG docker your-user

      // sudo usermod -aG docker lahiru

 

 

Verify docker is installed or not

05. docker -version

 

Test Docker with run hello world

06. docker run hello-world

07. See image => docker images

08. See running container => docker container ls

09. See container status => docker ps -a

Open eclipse and go to,             Window – Show View – Other - Type git on the folder and select git repositories. 05.   Now clone this repository at your desired location in which we are going to keep the project specific file . a)         a)  Step One.             b)  Step  Two .          c)    Step Three. Both projects are generated as bellows           d) Step Four  Open the gitingnore file and ignore the target folder of the project. All the class files which are generate with compile the code are store in target folder. Class file can be generated. Because of that we don’t commit that folder to git.           e) Step Five Open window – preference – filter fo

What is MicroService? MicroService යනු තනි application එකක් (Monolithic Application එකක්), එකිනෙක communicate කරගන පුළුවන් වෙන වෙනම deploy වන කුඩා කුඩා independent services වලට කැඩීමයි. Simply it is new way to develop application rather than traditional monolithic application. Companies which are using microservice.   Features of MicroService Architecture Small focused – main aim of microservice is simplicity.it can be rewrite in maintained without extra effort. Loosely coupled – development as well as deployment is quick. Language Neutral – few services can be Java, few is c# few can be python.it can be use depend on the service. Bounded Context – each microservice does not need to understand the implementation of the other microservice.

    Project can be download from         https://github.com/LahiruPriyankara/SpringBootAppTwo-MongoDB MongoDB Aggregation This groups values from multiple documents together and can perform variety of operations on that grouped data.it is going to return single result after the aggregation. Stages In Aggregation: Those operation are used in group of documents ( Used inside aggregation stages).  Unary Operation -  Unary operator perform operation for each documents. Type - Given the type of the filed. In the SQL we query select count and in the bracket Astrix this count for aggregation. It return the number of rows. This is same in mongoDB. db . employee . aggregate ([ { $group : { _id : "$gender" , genderCount : { $sum : 1 } } } ]) // $sum: 1 :1 - true db . employee . aggregate ([ { $group : { _id : "$gender" , maxAge : { $max : "$age" } } } ]) Bellow example is from  https://docs.mongodb.com/manual/aggregation/ Single Purpose Aggregation
