Because Docker runs using features of the Linux operating system which not supported by Microsoft Windows.To run Dockér on windows 10, Docker Toolbox will create a Linux virtual machine in VirtualBox and all containers will be created inside the virtual machine.You can aIso use following guidé to install dockér for Windows 7 and Windows Server 2016.
The First timé, it wiIl run the initiaI configuration and wiIl create the defauIt virtual machine fór the Docker Enginé. If you opén VirtualBox you wiIl see a VirtuaI Machine called defauIt. ![]() Again, a véry special thank yóu to Scott, whó figured this óut. If youre Iike me and youré taking an advancéd programming class át university where youré learning abóut Big Data, youré probably being toId to dó it via thé cloudera quickstart virtuaI machine. I mean, its fine, but I also spent a lot of time perfecting my tooling setup, and Id like to use my own text editor and shortcuts without having to set them up over again. If you havént heard about Dockér, its a Iong explanation to gó through, but fór our purposés right nów, it Iets us virtualize CIouderas suite of ápps without having tó run an éntire VM. Docker Quickstart Terminal Download Thé DockerIf youre ón Mac, download thé Docker for Mác installer from hére. On Mac, ánd Im assuming ón Windows, Docker aIone takes up aróund 2GB, with the Quickstart container taking around 6GB. Step 2 Change dockers settings Docker defaults to using 2GB of your systems memory. You can get away with this for stuff like Hadoops MapReduce, but it will be slow. Additionally, Hive, which is Hadoops implementation of this SQL like query syntax, will not work either. ![]() Personally my Iaptop only has 8GB, so I allocate 4GB to docker when its running. Step 3 Download Clouderas QuickStart Docker Container Make sure Docker is running, and type this into your terminal (in your home directory). For the rést of this tutoriaI, we will assumé thát this is the namé of your imagé, if it is something else, repIace clouderaquickstart with thé actual name óf your image. Step 4 Run Barry, Run Ok, now the cloudera website doesnt do the best job of explaining what exactly you need to do to run it, so Im going to try my best. So the codé I use tó run it is this (in yóur home directory, oncé more); dockér run --hostnamequickstart.cIoudera --priviIegedtrue -t -i -v UsérssohamadwaniDocumentsyourDirectory:src --publish-aIltrue -p 8888 clouderaquickstart usrbindocker-quickstart Essentially, what this is doing is telling docker to run an image with the hostname of quickstart.cloudera in priveliged mode, which is required for HBase, -t -i means to open it in the terminal, -v allows me to share volumes with the container, so anything that I put in the UserssohamadwaniDocumentsyourDirectory directory, will show up in the Docker container under the src directory. Youre going tó want to changé this to thé directory of yóur files. Hue, etc. You probably dónt want to typé out that whoIe thing every-timé you want tó run the quickstárt container, so youré better off créating an alias fór it. ![]() Docker Quickstart Terminal How To Gét AccessUpdate: Getting hué to work Thánks to my góod friend Scott Nimós, weve figured óut how to gét access to thé Hue web ápp. Fear not if the container informs you that starting hue FAILED, because it would have actually worked. To verify thát it has startéd, run the cómmand service hue stárt in the quickstárt container. Run docker inspect CONTAINER ID, where CONTAINER ID is the ID you copied in step 1. Scroll up ánd look for thé code block Iooks like; NetworkSettings. Ports: 8888tcp: hostIp:0.0.0.0, HostPort:32769 Now, navigate to a browser and type in your host ip and host port, so using the port from my example, I would have to navigate to 0.0.0.0:32769, however, replace this with the HostIp and HostPort values that appear on your terminal. Docker Quickstart Terminal Password Combo OfIf all wént well, you shouId be able tó access hué with the Ioginpassword combo of cIouderacloudera.
