How to use docker to modify Nginx files

DockerBuildKit is a modern image building backend. It can improve construction efficiency and maintainability by 1) parallel processing of independent construction steps, 2) more advanced caching mechanisms (such as remote cache reuse), and 3) structured output improves construction efficiency and maintainability, significantly optimizing the speed and flexibility of Docker image building. Users only need to enable the DOCKER_BUILDKIT environment variable or use the buildx command to activate this function.

To start, stop or restart Nginx, the specific commands depend on the system type and installation method. 1. For modern systems that use systemd (such as Ubuntu16.04, Debian8, CentOS7), you can use: sudosystemctlstartnginx, sudosystemctlstopnginx, sudosystemctlrestartnginx, and use sudosystemctlreloadnginx after configuration changes; 2. For old systems that use SysVinit, use the service command: sudoservicenginxstart,

Kubernetes is not a replacement for Docker, but the next step in managing large-scale containers. Docker is used to build and run containers, while Kubernetes is used to orchestrate these containers across multiple machines. Specifically: 1. Docker packages applications and Kubernetes manages its operations; 2. Kubernetes automatically deploys, expands and manages containerized applications; 3. It realizes container orchestration through components such as nodes, pods and control planes; 4. Kubernetes works in collaboration with Docker to automatically restart failed containers, expand on demand, load balancing and no downtime updates; 5. Applicable to application scenarios that require rapid expansion, running microservices, high availability and multi-environment deployment.

When encountering Docker problems, you should first locate the problem, which is problems such as image construction, container operation or network configuration, and then follow the steps to check. 1. Check the container log (dockerlogs or docker-composelogs) to obtain error information; 2. Check the container status (dockerps) and resource usage (dockerstats) to determine whether there is an exception due to insufficient memory or port problems; 3. Enter the inside of the container (dockerexec) to verify the path, permissions and dependencies; 4. Review whether there are configuration errors in the Dockerfile and compose files, such as environment variable spelling or volume mount path problems, and recommend that cleanbuild avoid cache dryness

A common way to create a Docker volume is to use the dockervolumecreate command and specify the volume name. The steps include: 1. Create a named volume using dockervolume-createmy-volume; 2. Mount the volume to the container through dockerrun-vmy-volume:/path/in/container; 3. Verify the volume using dockervolumels and clean useless volumes with dockervolumeprune. In addition, anonymous volume or binding mount can be selected. The former automatically generates an ID by Docker, and the latter maps the host directory directly to the container. Note that volumes are only valid locally, and external storage solutions are required across nodes.

There are three common ways to set environment variables in a Docker container: use the -e flag, define ENV instructions in a Dockerfile, or manage them through DockerCompose. 1. Adding the -e flag when using dockerrun can directly pass variables, which is suitable for temporary testing or CI/CD integration; 2. Using ENV in Dockerfile to set default values, which is suitable for fixed variables that are not often changed, but is not suitable for distinguishing different environment configurations; 3. DockerCompose can define variables through environment blocks or .env files, which is more conducive to development collaboration and configuration separation, and supports variable replacement. Choose the right method according to project needs or use multiple methods in combination
