Billie Rinaldi updated YARN-5505:
---------------------------------
Attachment: YARN-5505-yarn-native-services.001.patch
Attaching a first draft of the docker provider. Unit tests are passing with
this patch, but there are some Slider IT failures I am still looking into. To
specify the docker provider when launching an app, use the following:
{noformat}
slider create appName --provider docker --template appConfig.json --resources
resources.json
{noformat}
The docker image and start command are specified in the appConfig as follows:
{noformat}
"docker.image": "imageName",
"docker.startCommand": "startCommand",
{noformat}
Metainfo is no longer required, as this is only needed by the Slider agent. For
the docker provider, metainfo information is placed in the appConfig. Metainfo
items already handled in this patch are config files and packages/tarballs to
be localized by the AM.
Config files generated by the AM are specified in new appConfig properties
prefixed by "conf.", while the k/v config properties to appear in the config
files are specified under "site." (as they have been for agent apps):
{noformat}
"am.config.generation": "true",
"conf.myapp-site.type": "properties",
"conf.myapp-site.name": "/tmp/conf.properties",
"site.myapp-site.prop1": "val1",
"site.myapp-site.prop2": "val2",
{noformat}
Tarballs and other resources to be localized are specified with the prefix
"pkg.":
{noformat}
"pkg.myapp.type": "archive",
"pkg.myapp.name": "myapp-bin.tar.gz",
{noformat}

> The Slider AM has a pluggable portion called a provider. Currently the only
> provider implementation is the agent provider which contains the bulk of the
> agent-related Java code. We can implement a docker provider that does not use
> the agent and gets information it needs directly from the NM.
