In docker, solr represents an open source search platform, used to build search applications; XML files in a certain format can be submitted to the search engine server through http requests to generate indexes, or searches can be made through the "Http Get" operation. Request and get the returned result in XML format.

What is the role of solr in docker
Solr is an open source search platform used to build search applications. It is built on top of Lucene (full text search engine). Solr is enterprise-grade, fast and highly scalable. Applications built with Solr are highly complex and deliver high performance.
You can submit an XML file in a certain format to the search engine server through http requests to generate an index; you can also make a search request through Http Get operations and get the returned results in XML format.
Deploy Solr and install IKAnalyzer
Write yml file
version: '3.1' services: solr: build: ikanalyzer restart: always container_name: solr ports: - 8983:8983 volumes: - ./solrdata:/opt/solrdata
Dockerfile
FROM solr:7.1.0 # 创建 Core WORKDIR /opt/solr/server/solr RUN mkdir ik_core WORKDIR /opt/solr/server/solr/ik_core RUN echo 'name=ik_core' > core.properties RUN mkdir data RUN cp -r ../configsets/sample_techproducts_configs/conf/ . # 安装中文分词 WORKDIR /opt/solr/server/solr-webapp/webapp/WEB-INF/lib ADD ik-analyzer-solr5-5.x.jar .

Solr is a high-performance, Java-developed, Lucene-based full-text search server. At the same time, it has been extended to provide a richer query language than Lucene. It is also configurable, scalable and optimized for query performance. It also provides a complete function management interface. It is a very excellent Full-text search engine
Documents are added to a search collection via HTTP using XML. Querying the collection is also achieved by receiving an XML/JSON response via http. Its main features include: efficient and flexible caching function, vertical search function, highlighting search results, improving usability through index replication, providing a set of powerful Data Schema to define fields, types and settings for text analysis, and providing Web-based Management interface, etc.

The ways Docker can simplify development and operation and maintenance processes include: 1) providing a consistent environment to ensure that applications run consistently in different environments; 2) optimizing application deployment through Dockerfile and image building; 3) using DockerCompose to manage multiple services. Docker implements these functions through containerization technology, but during use, you need to pay attention to common problems such as image construction, container startup and network configuration, and improve performance through image optimization and resource management.

The relationship between Docker and Kubernetes is: Docker is used to package applications, and Kubernetes is used to orchestrate and manage containers. 1.Docker simplifies application packaging and distribution through container technology. 2. Kubernetes manages containers to ensure high availability and scalability. They are used in combination to improve application deployment and management efficiency.

Docker solves the problem of consistency in software running in different environments through container technology. Its development history has promoted the evolution of the cloud computing ecosystem from 2013 to the present. Docker uses Linux kernel technology to achieve process isolation and resource limitation, improving the portability of applications. In development and deployment, Docker improves resource utilization and deployment speed, supports DevOps and microservice architectures, but also faces challenges in image management, security and container orchestration.

Docker and virtual machines have their own advantages and disadvantages, and the choice should be based on specific needs. 1.Docker is lightweight and fast, suitable for microservices and CI/CD, fast startup and low resource utilization. 2. Virtual machines provide high isolation and multi-operating system support, but they consume a lot of resources and slow startup.

The core concept of Docker architecture is containers and mirrors: 1. Mirrors are the blueprint of containers, including applications and their dependencies. 2. Containers are running instances of images and are created based on images. 3. The mirror consists of multiple read-only layers, and the writable layer is added when the container is running. 4. Implement resource isolation and management through Linux namespace and control groups.

Docker simplifies the construction, deployment and operation of applications through containerization technology. 1) Docker is an open source platform that uses container technology to package applications and their dependencies to ensure cross-environment consistency. 2) Mirrors and containers are the core of Docker. The mirror is the executable package of the application and the container is the running instance of the image. 3) Basic usage of Docker is like running an Nginx server, and advanced usage is like using DockerCompose to manage multi-container applications. 4) Common errors include image download failure and container startup failure, and debugging skills include viewing logs and checking ports. 5) Performance optimization and best practices include mirror optimization, resource management and security improvement.

The steps to deploy containerized applications using Kubernetes and Docker include: 1. Build a Docker image, define the application image using Dockerfile and push it to DockerHub. 2. Create Deployment and Service in Kubernetes to manage and expose applications. 3. Use HorizontalPodAutoscaler to achieve dynamic scaling. 4. Debug common problems through kubectl command. 5. Optimize performance, define resource limitations and requests, and manage configurations using Helm.

Docker is an open source platform for developing, packaging and running applications, and through containerization technology, solving the consistency of applications in different environments. 1. Build the image: Define the application environment and dependencies through the Dockerfile and build it using the dockerbuild command. 2. Run the container: Use the dockerrun command to start the container from the mirror. 3. Manage containers: manage container life cycle through dockerps, dockerstop, dockerrm and other commands.
