How to view containers in docker

You can view Docker container details through the following command: docker ps: display the running container list docker inspect <container_id>: display the full configuration and status information docker logs <container_id>: view the log docker inspect -f '{{ .Config.Env }}' <container_id>: view the environment variable docker inspect -f '{{ .NetworkS

Docker uses yaml

YAML is used to configure containers, images, and services for Docker. To configure: For containers, specify the name, image, port, and environment variables in docker-compose.yml. For images, basic images, build commands, and default commands are provided in Dockerfile. For services, set the name, mirror, port, volume, and environment variables in docker-compose.service.yml.

Docker uses host network

Docker's host network mode allows containers to use host network resources. Features include: Sharing IP addresses and ports with the host, accessing the host file system, network configuration, and firewall. Notes include: security issues, resource conflicts and restrictions. Best practices recommend using this pattern when a container needs deep integration with the host, access to a specific resource, or is trusted. Alternatives include bridge mode, overlay network, and custom network.

What methods does Docker use to identify containers?

Docker通过以下方式标识容器：容器名称：唯一标识符，创建时指定。 Container ID: A unique identifier generated by Docker.摘要：基于映像内容生成的唯一标识符。标签：键值对，用于组织和标识容器。扩展网络别名：用于在多个容器之间发现的唯一别名。 Docker Swarm服务名称：引用特定容器的服务集合的名称。 Docker Engine API：允许通过名称、ID或摘要引用容器。

What methods does Docker use to identify images?

Docker uses four ways to identify images: mirror ID, mirror name, mirror tag, and summary. The mirror ID is unique and immutable, the mirror name is readable and usually consists of a repository name and a mirror name, the mirror tag is used to identify a specific version or variant, and the summary is based on the mirror content rather than metadata.

What platform Docker uses to manage public images

The Docker image hosting platform is used to manage and store Docker images, making it easy for developers and users to access and use prebuilt software environments. Common platforms include: Docker Hub: officially maintained by Docker and has a huge mirror library. GitHub Container Registry: Integrates the GitHub ecosystem. Google Container Registry: Hosted by Google Cloud Platform. Amazon Elastic Container Registry: Hosted by AWS. Quay.io: By Red Hat

Docker application development

Docker application development uses containers to package and deploy applications, providing isolation, portability, consistency, rapid deployment, and version control. The processes include writing code, creating Dockerfiles, building images, running containers, and deploying. Additionally, Docker volumes can be used for data persistence, networks enable secure communication between containers, and orchestration tools can manage large-scale deployments.

What does docker do

Docker is an open source container engine for building, deploying, and running applications. Its capabilities include: Containerization: Packaged applications and dependency isolation: Applications running in containers are isolated from each other Portability: Containers can be ported on different platforms and cloud environments Automation: Automated application building and deployment of process microservices: Ideal for building and managing components in microservice architectures

Docker uses macvlan

macvlan in Docker is a Linux kernel module that allows containers to have their own MAC address, enabling network isolation, performance improvement and direct interaction with the physical network. Using macvlan requires: 1. Install the kernel module; 2. Create a macvlan network; 3. Assign IP address segments; 4. Specify the macvlan network when container creation; 5. Verify the connection.

How to configure domain name access for docker applications

Configuring an application to access a specific domain name in a Docker environment requires the following steps: Create a user-defined network and specify the network using the --network option. When running the container, use the --publish option to map the port of the application container to the host port. Add a DNS record in the host system's /etc/hosts file to resolve the custom domain name to the container's IP address. You can access the application using a custom domain name.
