1 使用--mount 进行挂载,type的类型bind和volume,分别是挂载绑定和挂载数据卷,请问二者有何区别。 答:不同之处在于volume是docker自身管理的目录中的子目录,所以不存在权限引发的挂载的问题,并且目录路径是docker自身管理的,所以也不需要在不同的服务器上指定不同的路径 2 数据卷分为命名数据卷和匿名数据卷,二者有...
示例代码 下面是一个使用Docker Compose的示例,演示了如何配置Volumes和Mounts。 version:'3.8'services:web:image:nginx:alpineports:-"80:80"volumes:-web-data:/var/www/htmldeploy:mode:replicatedreplicas:2db:image:postgres:latestenvironment:POSTGRES_DB:dbnamePOSTGRES_USER:userPOSTGRES_PASSWORD:passwordvolumes:...
and change the ENTRYPOINT so that it points to a custom "init_script.sh" (wihch would be run as 'root' since I removedUSER postgres), this script would change permissions of/volume_dataso that 'postgres' can write on it, thensu postgresand execute the postgresql daemon ...
When you create a volume, it's stored within a directory on the Docker host. When you mount the volume into a container, this directory is what's mounted into the container. This is similar to the way that bind mounts work, except that volumes are managed by Docker and are isolated fro...
I’m trying to mount volume that is an NFS. I have this docker-compose file: version: "3.8" volumes: neonfs: driver: local driver_opts: type: nfs o: addr=172.26.209.22 device: :/space/home/cverond/varwwwhtml services: web: build: dockerfile: ./Dockerfile ports: - "80:80" enviro...
6. Volume Mappings With volume mappings, you will map a local directory to a directory inside the Docker container. This can be more tricky, because you must make some assumptions about the local system permissions, users, groups, etc. And often this just works fine because your local uid/...
Hello, I’m asking the Docker community for help because I’m facing a problem. I execute a docker-compose which launches a docker swarm stack, I want to mount an NFS volume but I get an error message. Error message >> …
Compose 是用于定义和运行多容器 Docker 应用程序的工具。通过 Compose,您可以使用 YML 文件来配置应用程序需要的所有服务。然后,使用一个命令,就可以从 YML 文件配置中创建并启动所有服务。 docker compose文件是一个yaml格式的文件,所以注意行首的缩进很严格,

$ docker run -id --mount type=volume,source=hello,target=/world ubuntu /bin/bash 我们创建了名称为 hello 的数据卷,然后把它挂在到容器中的 /world 目录。通过 inspect 命令查看容器的详情中的 "Mounts" 信息可以验证. 使用volume driver 把数据存储到其它地方 ...
