You can use the following configuration properties of the Data Flow server to customize how applications are deployed.
spring.cloud.deployer.local.workingDirectoriesRoot=java.io.tmpdir # Directory in which all created processes will run and create log files. spring.cloud.deployer.local.deleteFilesOnExit=true # Whether to delete created files and directories on JVM exit. spring.cloud.deployer.local.envVarsToInherit=TMP,LANG,LANGUAGE,"LC_.*. # Array of regular expression patterns for environment variables that will be passed to launched applications. spring.cloud.deployer.local.javaCmd=java # Command to run java. spring.cloud.deployer.local.shutdownTimeout=30 # Max number of seconds to wait for app shutdown. spring.cloud.deployer.local.javaOpts= # The Java options to pass to the JVM
When deploying the application you can also set deployer properties prefixed with
app.<name of application>, So for example to set Java options for the time application in the
ticktock stream, use the following stream deployment properties.
dataflow:> stream create --name ticktock --definition "time --server.port=9000 | log" dataflow:> stream deploy --name ticktock --properties "app.time.spring.cloud.deployer.local.javaOpts=-Xmx2048m -Dtest=foo"
As a convenience you can set the property
spring.cloud.deployer.local.memory to set the Java option
-Xmx. So for example,
dataflow:> stream deploy --name ticktock --properties "app.time.spring.cloud.deployer.local.memory=2048m"
At deployment time, if you specify an
-Xmx option in the
javaOpts property in addition to a value of the
memory option, the value in the
javaOpts property has precedence. Also, the
javaOpts property set when deploying the application has precedence over the Data Flow server’s
