+# JProfiler with Docker
+
+## Docker
+
+### DockerFile
+DockerFile should have JProfiler installation.
+```docker
+RUN wget <JProfiler file location> -P /tmp/ && \
+  tar -xzf /tmp/<JProfiler file> -C /usr/local && \
+  rm /tmp/<JProfiler file>
+
+EXPOSE <port>
+
+```
+
+e.g.)
+```docker
+RUN wget http://download-aws.ej-technologies.com/jprofiler/jprofiler_linux_9_2.tar.gz -P /tmp/ && \
+  tar -xzf /tmp/jprofiler_linux_9_2.tar.gz -C /usr/local &&\
+  rm /tmp/jprofiler_linux_9_2.tar.gz
+
+EXPOSE 8849
+
+```
+
+### Run
+```
+docker run -p <port>:<port> your-docker 
+```
+
+e.g.)
+```
+docker run -p 8849:8849 your-docker 
+```
+
+## JProfiler
+### Run Application with JProfiler Agent
+```
+java -jar my-app.jar -agentpath:/usr/local/jprofiler9/bin/linux-x64/libjprofilerti.so=port=<port>
+```
+
+e.g.)
+```
+java -jar my-app.jar -agentpath:/usr/local/jprofiler9/bin/linux-x64/libjprofilerti.so=port=8849
+```
+
+So in the `DockerFile`, it looks like
+
+```
+ENTRYPOINT ["java -jar","my-app.jar", 
+  "-agentpath:/usr/local/jprofiler9/bin/linux-x64/libjprofilerti.so=port=8849"]
+```
+
+1. Select '`Profile an application server, locally or remotely`'.
+2. If the target application is running on any specific server listed, select it. Otherwise, choose `Generic application`.
+3. Select `Linux X86/AMD64` for `Platform of the remote computer` on a remote computer.
+4. Select the JVM used in the Docker instance.
+5. To make JProfiler to wait for the application to start and send data, select `Wait for a connection from the JProfiler GUI`.
+6. Enter the remote address to the `Remote address`. If it's Docker for Mac, it is `localhost`. If Docker Machine is used, use the IP of the Docker Machine.
+7. Add the path to the JProfiler on the Docker where the jar file metioned above is using to the `Remote installation directory`. It looks like `/usr/local/jprofiler<version>`. e.g.) /usr/local/jprofiler9
+8. Set the port number or use the default (i.e. 8849).

+VisualVM with Docker
+=====================
+## Installation
+VisualVM comes with the JDK so it doesn't require any extra installation or payment if JDK is already installed.
+
+## DockerFile
+The following options should be added to java executable command.
+```
+-Dcom.sun.management.jmxremote=true
+-Dcom.sun.management.jmxremote.port=<port>
+-Dcom.sun.management.jmxremote.authenticate=false
+-Dcom.sun.management.jmxremote.ssl=false
+-Dcom.sun.management.jmxremote.local.only=false
+-Dcom.sun.management.jmxremote.rmi.port=<port>
+-Djava.rmi.server.hostname=<docker ip>
+```
+***
+
+So it should be like
+```
+ENTRYPOINT ["java -jar", "app.jar",
+  "-Dcom.sun.management.jmxremote=true",
+  "-Dcom.sun.management.jmxremote.port=<port>",
+  "-Dcom.sun.management.jmxremote.authenticate=false",
+  "-Dcom.sun.management.jmxremote.ssl=false",
+  "-Dcom.sun.management.jmxremote.local.only=false",
+  "-Dcom.sun.management.jmxremote.rmi.port=<port>",
+  "-Djava.rmi.server.hostname=<docker ip>"]
+```
+
+e.g.)
+```
+ENTRYPOINT ["java -jar", "my-app.jar",
+  "-Dcom.sun.management.jmxremote=true",
+  "-Dcom.sun.management.jmxremote.port=8849",
+  "-Dcom.sun.management.jmxremote.authenticate=false",
+  "-Dcom.sun.management.jmxremote.ssl=false",
+  "-Dcom.sun.management.jmxremote.local.only=false",
+  "-Dcom.sun.management.jmxremote.rmi.port=8849",
+  "-Djava.rmi.server.hostname=localhost"]
+```
+
+* **Docker for Mac** uses **Hyperkit** instead of **Docker Machine** through VirtualBox so the host location can be just **`localhost`** rather than the IP of the Docker Machine. If you're using Docker Machine, use the IP of the machine.
+
+## VisualVM
+Run `jvisualvm` which is located at `$JAVA_HOME/bin`.
+
+1. File -> `Add JMX Connection...`
+2. Enter the `host` and `port` (e.g. `localhost:8849`).
