+# Dockerfile for WSO2 Identity Server #
+
+This section defines the step-by-step instructions to build an [Rocky Linux](https://hub.docker.com/_/rockylinux) Linux based Docker image for WSO2 Identity Server `7.0.0`.
+
+## Prerequisites
+
+* [Docker](https://www.docker.com/get-docker) `v17.09.0` or above
+* [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) client
+
+## How to build an image and run
+
+##### 1. Checkout this repository into your local machine using the following Git client command.
+
+```
+git clone https://github.com/wso2/docker-is.git
+```
+
+>The local copy of the `dockerfiles/rocky/is` directory will be referred to as `IS_DOCKERFILE_HOME` from this point onwards.
+
+##### 2.  Build the Docker image.
+- Navigate to `<IS_DOCKERFILE_HOME>` directory. <br>
+  Execute `docker build` command as shown below.
+    + `docker build -t wso2is:7.0.0-rocky .`
+
+> Configure the URL of hosted wso2is-7.0.0 distribution as WSO2_SERVER_DIST_URL.
+
+> Tip - If you require the container to run with a different UID and GID, pass the preferred values of the UID and GID
+> as values for build arguments `USER_ID` and `USER_GROUP_ID` when building the image, as shown below. Note
+> that setting lower values for the UID and GID is not recommended.
++ `docker build -t wso2is:7.0.0-rocky --build-arg USER_ID=<UID> --build-arg USER_GROUP_ID=<GID> .`
+
+##### 3. Running the Docker image.
+
+- `docker run -it -p 9443:9443 wso2is:7.0.0-rocky`
+
+>Here, only port 9443 (HTTPS servlet transport) has been mapped to a Docker host port.
+You may map other container service ports, which have been exposed to Docker host ports, as desired.
+
+##### 4. Accessing management consoles.
+
+- To access the user interfaces, use the docker host IP and port 9443.
+    + Management Console: `https://<DOCKER_HOST>:9443/console`
+    + User Portal: `https://<DOCKER_HOST>:9443/myaccount`
+
+>In here, <DOCKER_HOST> refers to hostname or IP of the host machine on top of which containers are spawned.
+
+## How to update configurations
+
+Configurations would lie on the Docker host machine and they can be volume mounted to the container. <br>
+As an example, steps required to change the port offset using `deployment.toml` is as follows:
+
+##### 1. Stop the Identity Server container if it's already running.
+
+In WSO2 Identity Server version `7.0.0` product distribution, `deployment.toml` configuration file <br>
+can be found at `<DISTRIBUTION_HOME>/repository/conf`. Copy the file to some suitable location of the host machine, <br>
+referred to as `<SOURCE_CONFIGS>/deployment.toml` and change the `[server] -> offset` value to 1.
+
+##### 2. Grant read permission to `other` users for `<SOURCE_CONFIGS>/deployment.toml`.
+
+```
+chmod o+r <SOURCE_CONFIGS>/deployment.toml
+```
+
+##### 3. Run the image by mounting the file to container as follows:
+
+```
+docker run \
+-p 9444:9444 \
+--volume <SOURCE_CONFIGS>/deployment.toml:<TARGET_CONFIGS>/deployment.toml \
+wso2is:7.0.0-rocky
+```
+
+>In here, <TARGET_CONFIGS> refers to /home/wso2carbon/wso2is-7.0.0/repository/conf folder of the container.
