-SkyWalking Agent Deployment
-=============================
-
-The `dolphinscheduler-skywalking` module provides [SkyWalking](https://skywalking.apache.org/) monitor agent for the DolphinScheduler project.
-
-This document describes how to enable SkyWalking version 8.4+ support with this module (recommend using SkyWalking 8.5.0).
-
-## Installation
-
-The following configuration is used to enable the SkyWalking agent.
-
-### Through Environment Variable Configuration (for Docker Compose)
-
-Modify SkyWalking environment variables in `docker/docker-swarm/config.env.sh`:
-
-```
-SKYWALKING_ENABLE=true
-SW_AGENT_COLLECTOR_BACKEND_SERVICES=127.0.0.1:11800
-SW_GRPC_LOG_SERVER_HOST=127.0.0.1
-SW_GRPC_LOG_SERVER_PORT=11800
-```
-
-And run:
-
-```shell
-$ docker-compose up -d
-```
-
-### Through Environment Variable Configuration (for Docker)
-
-```shell
-$ docker run -d --name dolphinscheduler \
--e DATABASE_HOST="192.168.x.x" -e DATABASE_PORT="5432" -e DATABASE_DATABASE="dolphinscheduler" \
--e DATABASE_USERNAME="test" -e DATABASE_PASSWORD="test" \
--e ZOOKEEPER_QUORUM="192.168.x.x:2181" \
--e SKYWALKING_ENABLE="true" \
--e SW_AGENT_COLLECTOR_BACKEND_SERVICES="your.skywalking-oap-server.com:11800" \
--e SW_GRPC_LOG_SERVER_HOST="your.skywalking-log-reporter.com" \
--e SW_GRPC_LOG_SERVER_PORT="11800" \
--p 12345:12345 \
-apache/dolphinscheduler:1.3.8 all
-```
-
-### Through install_config.conf Configuration (for DolphinScheduler install.sh)
-
-Add the following configurations to `${workDir}/conf/config/install_config.conf`.
-
-```properties
-
-# SkyWalking config
-# note: enable SkyWalking tracking plugin
-enableSkywalking="true"
-# note: configure SkyWalking backend service address
-skywalkingServers="your.skywalking-oap-server.com:11800"
-# note: configure SkyWalking log reporter host
-skywalkingLogReporterHost="your.skywalking-log-reporter.com"
-# note: configure SkyWalking log reporter port
-skywalkingLogReporterPort="11800"
-
-```
-
-## Usage
-
-### Import Dashboard
-
-#### Import DolphinScheduler Dashboard to SkyWalking Server
-
-Copy the `${dolphinscheduler.home}/ext/skywalking-agent/dashboard/dolphinscheduler.yml` file into `${skywalking-oap-server.home}/config/ui-initialized-templates/` directory, and restart SkyWalking oap-server.
-
-#### View DolphinScheduler Dashboard
-
-If you have opened the SkyWalking dashboard with a browser before, you need to clear the browser cache.
