docker run IMAGE[:TAG][@DIGEST] docker create IMAGE[:TAG][@DIGEST] An image tag is the image version, which defaults to latest when omitted. Use the tag to run a container from specific version of an image. For example, to run version 24.04 of the ubuntu image: docker run ubuntu:24.0...
In this lesson, we will review an app that saves uploaded files to the filesystem. Then we will learn how to setup a persistent volume for the uploaded files so they can survive Docker container halts, restarts, stops and respawns. Dockerfile: FROMmhart/alpine-nodeWORKDIR/srvCOPY. .RUNmkdir...

Learn how to use Docker Compose to define and run multi-container applications with this detailed introduction to the tool.
③ 进入容器:docker exec -ti <CONTAINER ID> bash ④ 指定端口:docker run -d -p<宿主机端口>:<容器内端口> <IMAGE ID> 通过-p 参数指定宿主机与容器内的端口映射,如果不指定宿主机端口,将会随机映射一个宿主机端口。映射好端口后,宿主机外部就可以通过该端口访问容器了。
docker run --name nginxContainer -v v1:/usr/share/nginx/html -p80:80-d nginx ② 进入html数据卷所在位置,并修改HTML内容 # 查看html数据卷的位置 docker volume inspect v1 # 进入该目录 cd/var/lib/docker/volumes/html/_data # 修改文件 ...
docker run -it --name=c1 -v /root/data:/root/data_container centos:7 /bin/bash 关闭容器,可以看到数据卷数据文件还在 docker stop c1 宿主机目录还在 删除容器c1 docker rm c1 宿主机目录还在 重新恢复c1 docker run -it --name=c1 -v ~/data:/root/data_container centos:7 /bin/bash ...
这里要解释一个概念 containers 和 task ,在 docker 里面 container 概念被弱化 ,将 containers 和 task 整合在一起,基于 docker run 可以运行容器。 ctr 中 containers 是镜像实例化的一个虚拟环境,提供一个磁盘,模拟空间,就好比你电脑处于关机状态一样。
docker export保存的是容器(container),docker import用来载入容器包 docker export [容器ID|Name] > xxx.tar 导出容器会丢失历史记录和元数据,类似与快照 docker import xxx.tar newname:tag 启动export与import命令导出导入的镜像必须加/bin/bash或者其他/bin/sh,否则会报错 docker run -itd --name web2 web:...
