What guarantees are required for a complete commercial Web service? I believe that most people do not understand, in order to let you better understand, the editor summed up the following content, do not say much, let's look down together.

1, full technology stack

Unlike a Demo demo, a valuable Web service for business is fully functional, with service assurance and monitoring mechanisms. Special emphasis on the cache system, if all read and write the database directly without adding the cache mechanism, then once the number of users increases, the system will almost certainly collapse.

1) Database

2) caching system

3) message queue

4) document service

5) Authentication

6) Asynchronous task scheduling

7) Log system

8) Service monitoring

9) no, no, no.

2, system architecture

The schematic diagram is as follows:

3, automatic build

After the development is completed and the test passes, submitting the code triggers the automatic build system.

Ali Cloud Container Image Service provides Docker image repository hosting, configures project code Git repository and construction rules, and implements cloud compilation and packaging with Dockerfile, eliminating the need for commonly used Jenkins build servers.

4, one-click deployment

Docker is an open source application container engine that packages applications and dependencies into a portable image, deploys to a server and runs in a Container container instance.

Resource orchestration Docker-compose defines and runs an application system composed of multiple containers, declares each service through the docker-compose.yml file, and completes the creation and startup of the application as a whole.

We use Docker to deploy applications quickly and efficiently. We first look at the operation steps and usage time:

Operation

Script

Usage time

Resource choreography, configuration mirroring

Docker-compose.yml

-

Install Docker,Ubuntu server available scripts

Docker.sh

-

Pull the image and download it when there is an update

Pull.sh

-

Start the service container

Up.sh

10s

View the running log

Logs.sh

-

Out of Service

Down.sh

15s

Take the full deployment of Web service scaffolding as an example, the code script file:

Https://github.com/jextop/StarterDeploy

Automatically install Docker in ├── docker.sh # Ubuntu environment

├── docker-compose.yml # resource orchestration file to configure individual services

├── pull.sh # pull the required Docker image

├── up.sh # starts the dependent runtime with one click

├── logs.sh # View the container running log

├── down.sh # stop the running environment

1) install Docker

The Ubuntu server can run the script docker.sh to install automatically

Https://docs.docker.com/install/linux/docker-ce/ubuntu/

Https://docs.docker.com/docker-for-windows/install/

2) pull.sh pulls the image

Pull the required images in batches, and view them on docker images after completion:

3) up.sh startup container

The docker-compose up-d command is encapsulated in the script. After startup, docker ps views the container instance:

4) logs.sh view log

Custom commands highlight important information:

Docker-compose logs-ft | grep-- color-I-e error-e warn-e version-e exception

5) Open the management backend and view the service

6) down.sh stops service

Run docker-compose down-- remove-orphans to stop and delete the container:
