+
+A:
+```
+./bin/pulsar-admin clusters list
+./bin/pulsar-admin clusters get cluster-name (eg, standalone)
+```
+
+The following results are correct:
+```
+./bin/pulsar-admin clusters get standalone
+{
+ "serviceUrl" : "http://127.0.0.1:8080";,
+ "brokerServiceUrl" : "pulsar://127.0.0.1:6650"

+```
+Your network should be connected to serviceUrl's network.
+
+If these two domain names are set incorrectly, please use the
`./bin/pulsar-admin clusters update` command to update them to be correct.
+
+```
+./bin/pulsar-admin clusters update --broker-url http://broker-ip:6605 --url
http://broker-ip:8080 cluster-name (eg, standalone)
+```
+Releated issue: https://github.com/apache/pulsar-manager/issues/292
+
+
+Q: Pulsar Manager keeps saying "This environment is error. Please check it"
+
+Reason: Your pulsar manager service cannot connect with your pulsar cluster
network.
+
+A: it's because _pulsar_ and _pulsar-manger_ runs in different containers
with theirself localhosts (each container just know itself `localhost`).
+you should either run these two containers in one network using something like
docker composer, or set `--network host` in your command, something like this:
+```bash
+docker run --rm --network host -it -e REDIRECT_HOST=http://localhost -e
REDIRECT_PORT=9527 -e DRIVER_CLASS_NAME=org.postgresql.Driver -e
URL='jdbc:postgresql://127.0.0.1:5432/pulsar_manager' -e USERNAME=pulsar -e
PASSWORD=pulsar -e LOG_LEVEL=DEBUG -v $PWD:/data

+
+Q: Pulsar Manager keeps saying "This environment is error. Please check it"
+
+Reason: Your pulsar manager service cannot connect with your pulsar cluster
network.
+
+A: it's because _pulsar_ and _pulsar-manger_ runs in different containers
with theirself localhosts (each container just know itself `localhost`).
+you should either run these two containers in one network using something like
docker composer, or set `--network host` in your command, something like this:
+```bash
+docker run --rm --network host -it -e REDIRECT_HOST=http://localhost -e
REDIRECT_PORT=9527 -e DRIVER_CLASS_NAME=org.postgresql.Driver -e
URL='jdbc:postgresql://127.0.0.1:5432/pulsar_manager' -e USERNAME=pulsar -e
PASSWORD=pulsar -e LOG_LEVEL=DEBUG -v $PWD:/data

+
+### Troubleshooting steps for Pulsar Manager
+
+1. check whether pulsar cluster is normal
+
+```
+curl -v http://webservice-url:port/metrics/
+
+For example:
+curl -v http://localhost:8080/metrics/
+```
+
+2. Check the cluster configuration. A should be your real service address and
cannot be filled in casually
+
+```
+./bin/pulsar-admin clusters list
+./bin/pulsar-admin clusters get cluster-name (eg, standalone)
+```
+

+
+Reason: The webservice URL configured by pulsar cluster when initializing
metadata is inconsistent with the actual webservice URL.
+
+A:
+```
+./bin/pulsar-admin clusters list
+./bin/pulsar-admin clusters get cluster-name (eg, standalone)
+```
+
+The following results are correct:
+```
+./bin/pulsar-admin clusters get standalone
+{
+ "serviceUrl" : "http://127.0.0.1:8080";,
+ "brokerServiceUrl" : "pulsar://127.0.0.1:6650"
+}
+```
+Your network should be connected to serviceUrl's network.
+
+If these two domain names are set incorrectly, please use the
`./bin/pulsar-admin clusters update` command to update them to be correct.
+
+```
+./bin/pulsar-admin clusters update --broker-url http://broker-ip:6605 --url
http://broker-ip:8080 cluster-name (eg, standalone)
+```

+
+
+Q: Pulsar Manager keeps saying "This environment is error. Please check it"
+
+Reason: Your pulsar manager service cannot connect with your pulsar cluster
network.
+
+A: it's because _pulsar_ and _pulsar-manger_ runs in different containers
with theirself localhosts (each container just know itself `localhost`).
+you should either run these two containers in one network using something like
docker composer, or set `--network host` in your command, something like this:
+```bash
+docker run --rm --network host -it -e REDIRECT_HOST=http://localhost -e
REDIRECT_PORT=9527 -e DRIVER_CLASS_NAME=org.postgresql.Driver -e
URL='jdbc:postgresql://127.0.0.1:5432/pulsar_manager' -e USERNAME=pulsar -e
PASSWORD=pulsar -e LOG_LEVEL=DEBUG -v $PWD:/data
apachepulsar/pulsar-manager:v0.1.0 /bin/sh
+```
+

+
+
+### Troubleshooting steps for Pulsar Manager
+
+1. check whether pulsar cluster is normal
+
+```
+curl -v http://webservice-url:port/metrics/
+
+For example:
+curl -v http://localhost:8080/metrics/
+```
+
+2. Check the cluster configuration. A should be your real service address and
cannot be filled in casually
+
+```
+./bin/pulsar-admin clusters list
+./bin/pulsar-admin clusters get cluster-name (eg, standalone)
+```
+
+The following results are correct:
+```
+./bin/pulsar-admin clusters get standalone
+{
+ "serviceUrl" : "http://127.0.0.1:8080";,
+ "brokerServiceUrl" : "pulsar://127.0.0.1:6650"
+}
+```
+Your network should be connected to serviceUrl's network.
+
+If these two domain names are set incorrectly, please use the
`./bin/pulsar-admin clusters update` command to update them to be correct.
