![]() ![]() I have to admit that the way I chosed to start with the driver from yp-engineering was really arbitrary. Let’s start by installing the necessary components: $ sudo apt-get install -y golang librados-dev librbd-dev ceph-common xfsprogs Thus I don’t much knowledge about the others and I can not provide you with much feedback. The volume plugin has 2 different methods to provision volumes: size=20480: RBD Image size to Create ( in MB) (default: 20480=20GB)Īs you see, the RBD volume plugin supports several options cluster name, user remove= false: Can Remove (destroy) RBD Images (default: false, volume will be renamed zz_name) pool= "rbd": Default Ceph Pool for RBD operations plugins= "/run/docker/plugins": Docker plugin directory for socket name= "rbd": Docker plugin name for use on -volume-driver option mount= "/var/lib/docker/volumes": Mount directory for volumes on host fs= "xfs": FS type for the created RBD Image (must have mkfs.type) create= false: Can auto Create RBD Images $ go get /yp-engineering/rbd-docker-plugin CONVOY PLUGIN VS DOCKER FOR VOLUME INSTALL manually, where you have to create the RBD image and put a filesystem on it by yourself. This is interesting when you know that the size of each volume can vary. $ sudo ceph auth get-or-create client.docker mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=docker' -o /etc/ceph/ The service can work with systemd with this unit file.įor the purpose of this tutorial, I will run it through stdout.īefore starting the service, I am going to configure Ceph for it: $ sudo ceph osd pool create docker 128 automatically, where the plugin will create the image and the filesystem for you.If it does not you should probably configure the plugin to do it for you. Let’s start the service: $ sudo rbd-docker-plugin -create -user=docker -pool=docker & I like the fact that the volume plugin can configure the volume for me so I will configure it to do so. The driver writes a socket under /run/docker/plugins/rbd.sock, this socket will be used by Docker to perform the necessary actions (create the volume, do the bindmount etc…). mapped the image and bindmounted the filesystem to the containerĪfter you shutdown the container, the volume will persist (if not using -rm to run your container) so you can easily run a new container and re-use it.ĭev/disk/by-label/cloudimg-rootfs 158G 13G 139G 9% /etc/hosts Now I am going to run a ‘bash’ container to inspect what is happening: $ sudo docker run -it -volume-driver=rbd -volume foo:/mnt/foo ceph/base bashįilesystem Size Used Avail Use% Mounted on CONVOY PLUGIN VS DOCKER FOR VOLUME DRIVER.Sbraaa! I think I will also give a look at the multi-filesystem drivers ( Flocker, Convoy, Rexray) as they bring interesting perspectives to the volume plugins.Android SDK development environment Docker image CONVOY PLUGIN VS DOCKER FOR VOLUME DRIVERS It contains the complete Android SDK enviroment, is able to perform all regular Android jobs. Solves the problem of " It works on my machine, but not on XXX machine". Infer), which has complex dependencies might be in conflict with your local environment. Installing the tool within a Docker container is the easiest and perfect solution. Works out of the box as an Android CI build enviroment.
