Configuring an Instance from the Command Line
As described in Deploying From the Command Line, the starting and configuration of an instance has to be done in its entirety on one line.
The options available can be seen by running the JAR with the
or by consulting the
Payara Micro Command Line Options
section in the
The general structure of starting, configuring, and deploying an application to an instance is as follows:
java -jar payara-micro.jar _--option1_ _--option2_ ...
As an example, see below for starting an instance with a non-default HTTP port:
java -jar payara-micro.jar --port 2468
Read configuration from a file
--domainConfig option, it is possible to define multiple options in a
configuration file. This option would override the default Payara Micro configuration
completely. The provided file must conform to the same structure as the
file in a Payara Server domain.
--rootDir option sets the root configuration directory and saves the
configuration across restarts. If empty, this directory will be filled by the
default configuration, including the
If specifying multiple options at once, the following precedence is followed:
rootDir < domainConfig < autoBindHttp | autoBindSsl < port | sslPort
In human language:
The domain.xml in the directory specified by the rootDir option (if one exists) is overridden by the domain.xml specified with the
The HTTP and HTTPS port numbers specified in either of these domain.xml files are overridden to be the default values of 8080 and 8081 when the
autoBindSsloptions are enabled respectively.
These default port values are then overridden in turn by the port numbers specified with the
