Eric Badger updated YARN-3853: ------------------------------ Labels: Docker (was: ) > Add docker container runtime support to LinuxContainterExecutor > --------------------------------------------------------------- > > Key: YARN-3853 > URL: https://issues.apache.org/jira/browse/YARN-3853 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Sidharta Seethana > Assignee: Sidharta Seethana > Priority: Major > Labels: Docker > Fix For: 2.8.0, 3.0.0-alpha1 > > Attachments: YARN-3853.001.patch, YARN-3853.002.patch > > > Create a new DockerContainerRuntime that implements support for docker > containers via container-executor. LinuxContainerExecutor should default to > current behavior when launching containers but switch to docker when > requested. > Overview > === > The current mechanism of launching/signaling containers is moved to its own > (default) container runtime. In order to use docker container runtime a > couple of environment variables have to be set. This will have to be > revisited when we have a first class client side API to specify different > container types and associated parameters. Using ‘pi’ as an example and using > a custom docker image, this is how you could use the docker container runtime > (LinuxContainerExecutor must be in use and the docker daemon needs to be > running) : > {code} > export > YARN_EXAMPLES_JAR=./share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar > bin/yarn jar $YARN_EXAMPLES_JAR pi > -Dmapreduce.map.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk" > > -Dyarn.app.mapreduce.am.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk" > > -Dmapreduce.reduce.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=ashahab/hadoop-trunk" > 4 1000 > {code} > > LinuxContainerExecutor can delegate to either runtime on a per container > basis. If the docker container type is selected, LinuxContainerExecutor > delegates to the DockerContainerRuntime which in turn uses docker support in > the container-executor binary to launch/manage docker containers ( see > YARN-3852 ) . -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
