+
+ Thank you for contributing! We will try to test and integrate the change as soon as we can, but be aware we have many GitHub repositories to manage and can't immediately respond to every request. There is no need to bump or check in on a pull request (it will clutter the discussion of the request).

+ Also don't be worried if the request is closed or not integrated sometimes the priorities of Bitnami might not match the priorities of the pull request. Don't fret, the open source community thrives on forks and GitHub makes it easy to keep your changes in a forked repo.

+# Contributing Guidelines
+
+Contributions are welcome via GitHub Pull Requests. This document outlines the process to help get your contribution accepted.
+
+Any type of contribution is welcome: new features, bug fixes, documentation improvements, etc.
+
+## How to Contribute
+
+1. Fork this repository, develop, and test your changes.
+2. Submit a pull request.
+
+### Requirements
+
+When submitting a PR make sure that:
+- It must pass CI jobs for linting and test the changes (if any).
+- It must follow [container best practices](https://engineering.bitnami.com/articles/best-practices-writing-a-dockerfile.html).
+- The title of the PR is clear enough.
+- If necessary, add information to the repository's `README.md`.
+
+#### Sign Your Work
+
+The sign-off is a simple line at the end of the explanation for a commit. All commits needs to be signed. Your signature certifies that you wrote the patch or otherwise have the right to contribute the material. The rules are pretty simple, you only need to certify the guidelines from [developercertificate.org](https://developercertificate.org/).
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@example.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your commit automatically with `git commit -s`.
+
+Note: If your git config information is set properly then viewing the `git log` information for your commit will look something like this:
+
+```
+Author: Joe Smith <joe.smith@example.com>
+Date:   Thu Feb 2 11:41:15 2018 -0800
+
+    Update README
+
+    Signed-off-by: Joe Smith <joe.smith@example.com>
+```
+
+Notice the `Author` and `Signed-off-by` lines match. If they don't your PR will be rejected by the automated DCO check.
+
+### PR Approval and Release Process
+
+1. Changes are manually reviewed by Bitnami team members usually within a business day.
+2. Once the changes are accepted, the PR is tested (if needed) into the Bitnami CI pipeline, the container is deployed and tested (verification and functional tests) using docker-compose and Helm (if there is an associated Helm Chart).
+3. The PR is merged by the reviewer(s) in the GitHub `master` branch.
+4. Then our CI/CD system is going to push the container image to the different registries including the recently merged changes.
+
+***NOTE***: Please note that, in terms of time, may be a slight difference between the appearance of the code in GitHub and the image with the changes in the different registries.

+# Kong packaged by Bitnami
+
+## What is Kong?
+
+> Kong is an open source Microservice API gateway and platform designed for managing microservices requests of high-availability, fault-tolerance, and distributed systems.
+
+[Overview of Kong](https://konghq.com/kong-community-edition/)
+
+Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
+
+## TL;DR
+
+```
+$ docker run --name kong bitnami/kong:latest
+```
+
+### Docker Compose
+
+```console
+$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-kong/master/docker-compose.yml > docker-compose.yml
+$ docker-compose up -d
+```
+
+## Why use Bitnami Images?
+
+* Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
+* With Bitnami images the latest bug fixes and features are available as soon as possible.
+* Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
+* All our images are based on [minideb](https://github.com/bitnami/minideb) a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
+* All Bitnami images available in Docker Hub are signed with [Docker Content Trust (DCT)](https://docs.docker.com/engine/security/trust/content_trust/). You can use `DOCKER_CONTENT_TRUST=1` to verify the integrity of the images.
+* Bitnami container images are released daily with the latest distribution packages available.
+
+> This [CVE scan report](https://quay.io/repository/bitnami/kong?tab=tags) contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.
+
+## Why use a non-root container?
+
+Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers [in our docs](https://docs.bitnami.com/tutorials/work-with-non-root-containers/).
+
+## Supported tags and respective `Dockerfile` links
+
+Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers/).
+
+
+* [`2`, `2-debian-10`, `2.8.1`, `2.8.1-debian-10-r1`, `latest` (2/debian-10/Dockerfile)](https://github.com/bitnami/bitnami-docker-kong/blob/2.8.1-debian-10-r1/2/debian-10/Dockerfile)
+
+Subscribe to project updates by watching the [bitnami/kong GitHub repo](https://github.com/bitnami/bitnami-docker-kong).
+
+## Get this image
+
+The recommended way to get the Bitnami Kong Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/kong).
+
+```console
+$ docker pull bitnami/kong:latest
+```
+
+To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/kong/tags/) in the Docker Hub Registry.
+
+```console
+$ docker pull bitnami/kong:[TAG]
+```
+
+If you wish, you can also build the image yourself.
+
+```console
+$ docker build -t bitnami/kong:latest 'https://github.com/bitnami/bitnami-docker-kong.git#master:2/debian-10'
+```
+
+## Connecting to other containers
+
+Using [Docker container networking](https://docs.docker.com/engine/userguide/networking/), a different server running inside a container can easily be accessed by your application containers and vice-versa.
+
+Containers attached to the same network can communicate with each other using the container name as the hostname.
+
+### Using the Command Line
+
+#### Step 1: Create a network
+
+```console
+$ docker network create kong-network --driver bridge
+```
+
+#### Step 2: Launch the Kong container within your network
+
+Use the `--network <NETWORK>` argument to the `docker run` command to attach the container to the `kong-network` network.
+
+```console
+$ docker run --name kong-node1 --network kong-network bitnami/kong:latest
+```
+
+#### Step 3: Run another containers
+
+We can launch another containers using the same flag (`--network NETWORK`) in the `docker run` command. If you also set a name to your container, you will be able to use it as hostname in your network.
+
+## Configuration
+
+The Bitnami Docker Kong can be easily setup with the following environment variables:
+
+- `KONG_PROXY_LISTEN_ADDRESS`: Address to which Kong Proxy service is bound to. Default: **0.0.0.0**
+- `KONG_PROXY_HTTP_PORT_NUMBER`: The port Kong Proxy is listening for HTTP requests. Default: **8000**
+- `KONG_PROXY_HTTPS_PORT_NUMBER`: The port Kong Proxy is listening for HTTPS requests. Default: **8443**
+- `KONG_ADMIN_LISTEN_ADDRESS`: Address to which Kong Admin service is bound to. Default: **127.0.0.1**
+- `KONG_ADMIN_HTTP_PORT_NUMBER`: The port Kong Admin is listening for HTTP requests. Default: **8001**
+- `KONG_ADMIN_HTTPS_PORT_NUMBER`: The port Kong Admin is listening for HTTPS requests. Default: **8444**
+- `KONG_MIGRATE`: Whether to automatically run Kong migration scripts on this node. In a cluster, only one node should have this flag enabled. Default: **no**
+- `KONG_EXIT_AFTER_MIGRATE`: Whether to exit after performing the migration (it will not launch the Kong daemon). This is useful using the container in Jobs and Cron Jobs. Default: **no**
+
+This container also supports configuring Kong via environment values starting with `KONG_`. For instance, by setting the `KONG_LOG_LEVEL` environment variable, Kong will take into account this value rather than the property set in `kong.conf`. It is recommended to set the following environment variables:
+
+- `KONG_DATABASE`: Database type used. Valid values: **postgres**, **cassandra** or **off**. Default: **postgres**
+- For PostgreSQL database: `KONG_PG_HOST`, `KONG_PG_PORT`, `KONG_PG_TIMEOUT`, `KONG_PG_USER`, `KONG_PG_PASSWORD`.
+- For Cassandra database: `KONG_CASSANDRA_CONTACT_POINTS`, `KONG_CASSANDRA_PORT`, `KONG_CASSANDRA_KEYSPACE`, `KONG_CASSANDRA_CONSISTENCY`, `KONG_CASSANDRA_USERNAME`, `KONG_CASSANDRA_PASSWORD`, `KONG_CASSANDRA_LB_POLICY`, `KONG_CASSANDRA_REPL_STRATEGY`, `KONG_CASSANDRA_REPL_FACTOR`, `KONG_CASSANDRA_DATA_CENTERS`.
+
+Check the official [Kong Configuration Reference](https://docs.konghq.com/latest/configuration/#environment-variables) for the full list of configurable properties.
+
+### Full configuration
+
+The image looks for Kong the configuration file in `/opt/bitnami/kong/conf/kong.conf`, which you can overwrite using your own custom configuration file.
+
+```console
+$ docker run --name kong \
+  -e KONG_DATABASE=off \
+  -v /path/to/kong.conf:/opt/bitnami/kong/conf/kong.conf \
+  bitnami/kong:latest
+```
+
+or using Docker Compose:
+
+```yaml
+version: '2'
+
+services:
+  kong:
+    image: 'bitnami/kong:latest'
+    ports:
+      - '8000:8000'
+      - '8443:8443'
+    environment:
+      # Assume we don't want data persistence for simplicity purposes
+      - KONG_DATABASE=off
+    volumes:
+      - /path/to/kong.conf:/opt/bitnami/kong/conf/kong.conf
+```
+
+## Logging
+
+The Bitnami Kong Docker image sends the container logs to `stdout`. To view the logs:
+
+```console
+$ docker logs kong
+```
+
+You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver.
+
+## Understand the structure of this image
+
+The Bitnami Kong Docker image is built using a Dockerfile with the structure below:
+
+```Dockerfile
+FROM bitnami/minideb
+
+ENV ...
+
+## Install required system packages and dependencies
+RUN install_packages xxx yyy zzz
+RUN . /opt/bitnami/scripts/libcomponent.sh && component_unpack && component_unpack "kong" "aa.bb.cc-dd"
+
+COPY rootfs /
+ENV ...
+
+EXPOSE 8080 8443
+ENTRYPOINT [ "/opt/bitnami/scripts/kong/entrypoint.sh" ]
+CMD [ "/opt/bitnami/scripts/kong/run.sh" ]
+```
+
+The Dockerfile has several sections related to:
+
+- Components installation
+- Components static configuration
+- Environment variables
+- Volumes
+- Ports to be exposed
+- Working directory and user
+  - Note that once the user is set to 1001, unprivileged commands cannot be executed any longer.
+- Entrypoint and command
+  - Take into account that these actions are not executed until the container is started.
+
+## Customize this image
+
+The Bitnami Kong Docker image is designed to be extended so it can be used as the base image for your custom API service.
+
+> Note: Read the [previous section](#understand-the-structure-of-this-image) to understand the Dockerfile structure before extending this image.
+
+### Extend this image
+
+Before extending this image, please note it is possible there are certain ways you can configure Kong using the original:
+
+- [Configuring Kong via environment variables](#configuration).
+- [Changing the 'kong.conf' file](#full-configuration).
+
+If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:
+
+```Dockerfile
+FROM bitnami/kong
+### Put your customizations below
+...
+```
+
+Here is an example of extending the image with the following modifications:
+
+- Install the `vim` editor
+- Modify the Kong configuration file
+- Modify the ports used by Kong
+- Change the user that runs the container
+
+```Dockerfile
+FROM bitnami/kong
+LABEL maintainer "Bitnami <containers@bitnami.com>"
+
+### Change user to perform privileged actions
+USER 0
+### Install 'vim'
+RUN install_packages vim
+### Revert to the original non-root user
+USER 1001
+
+### Disable anonymous reports
+## Keep in mind it is possible to do this by setting the KONG_ANONYMOUS_REPORTS=off environment variable
+RUN sed -i -r 's/#anonymous_reports = on/anonymous_reports = off/' /opt/bitnami/kong/conf/kong.conf
+
+### Modify the ports used by Kong by default
+## It is also possible to change these environment variables at runtime
+ENV KONG_PROXY_HTTP_PORT_NUMBER=8080
+ENV KONG_ADMIN_HTTP_PORT_NUMBER=8081
+EXPOSE 8080 8081 8443 8444
+
+### Modify the default container user
+USER 1002
+```
+
+Based on the extended image, you can use a Docker Compose file like the one below to add other features:
+
+- Configure Kong via environment variables
+- Override the entire `kong.conf` configuration file
+
+```yaml
+version: '2'
+services:
+  kong:
+    build: .
+    ports:
+      - '80:8080'
+      - '443:8443'
+    volumes:
+      - ./config/kong.conf:/opt/bitnami/kong/conf/kong.conf
+    environment:
+      # Assume we don't want data persistence for simplicity purposes
+      - KONG_DATABASE=off
+volumes:
+  data:
+    driver: local
+```
+
+## Maintenance
+
+### Upgrade this image
