The specific command to run inside the Docker instance is specific for the machine that is configured inside eMagiz Design & Deploy Architectures. It can be found inside the eMagiz iPaaS portal under Deploy Architecture. At the runtime connector, there is a right click option called Deploy Agent. That presents either the command or the location where that agent is installed. In case the command is presented it means that this machine is not yet equipped with the eMagiz Deploy agent. The command can be executed inside the Linux command prompt on the on-premises server. 18 + 19 +Once the agent is installed, eMagiz can manage the machine to deploy new runtimes and or update runtimes as needed. Also the container runtime can be controlled with start, stop, et commands.
