Switch Domain¶
Note
If HTTPS was previously enabled, you need to prepare the certificate for the new domain in advance. This domain replacement assumes dataflux.cn is replaced with guance.com.
Introduction¶
This article will explain how to replace the domain of Guance. The main steps are as follows:
- Modify the domain in Launcher
- Update all domains in configmap
- Add certificate Secret (optional)
- Modify all ingress domains
- Restart services
Scope of Impact¶
Guance Studio will be unavailable, approximately 15-30 minutes.
Operation Steps¶
Step One: Modify the domain and certificate name in Launcher¶
- Open the settings in the top-right corner of Launcher
- Click on the domain
- Modify the domain and save.
Step Two: Modify all domains in configmap¶
- You can execute the following script to back up:
NAMESPACE="forethought-core forethought-kodo forethought-webclient func2 middleware utils launcher"
for i in $NAMESPACE;
do
for o in $(kubectl get cm -n $i --no-headers 2>/dev/null |awk {'print $1'});
do
filename=cm-$i-$o.yaml
kubectl get cm $o -n $i -o yaml > $filename
echo $i $o
done
done
- Execute the following script to modify the address:
Note
You need to replace the variables OLD_VALUE and NEW_VALUE.
# Set the key-value pairs to be replaced
OLD_VALUE="dataflux.cn"
NEW_VALUE="guance.com"
NAMESPACE="forethought-core forethought-kodo forethought-webclient func2 middleware utils launcher"
for i in $NAMESPACE;
do
for configmap in $(kubectl get configmaps -o name -n $i 2>/dev/null |awk {'print $1'});
do
#echo $configmap
# kubectl get $configmap -n $i -o yaml |grep $OLD_VALUE
if [[ `kubectl get $configmap -n $i -o yaml |grep $OLD_VALUE` ]]; then
echo "$i $configmap has $(kubectl get configmaps -n $i -o yaml |grep -c $OLD_VALUE) occurrences"
kubectl get $configmap -n $i -o yaml | \
sed "s/${OLD_VALUE}/${NEW_VALUE}/g" | \
kubectl apply -f -
fi
done
done
Step Three: Add certificate Secret (optional)¶
- Open the settings in the top-right corner of Launcher
- Click on "Update TLS Certificate for Domain"
- Modify the TLS certificate and save.
Step Four: Modify all Ingress domains¶
Note
If DataWay is installed using host mode, you need to modify the remote_host parameter of DataWay.
You can execute the following script to back up:
NAMESPACE="forethought-core forethought-kodo forethought-webclient func2 middleware utils launcher"
for i in $NAMESPACE;
do
for ing in $(kubectl get ing -n $i -o jsonpath='{.items[*].metadata.name}');
do
filename=ing-$i-$ing.yaml
kubectl get ing $ing -n $i -o yaml > $filename
done
done
Execute the following script to modify the address:
OLD_VALUE="dataflux.cn"
NEW_VALUE="guance.com"
NAMESPACE="forethought-core forethought-kodo forethought-webclient func2 middleware utils launcher"
for i in $NAMESPACE;
do
for ing in $(kubectl get ing -n $i -o jsonpath='{.items[*].metadata.name}');
do
if [[ `kubectl get ing $ing -n $i -o yaml |grep $OLD_VALUE` ]]; then
echo "$i $ing has $(kubectl get ing $ing -n $i -o yaml |grep -c $OLD_VALUE) occurrences"
kubectl get ing $ing -n $i -o yaml | \
sed "s/${OLD_VALUE}/${NEW_VALUE}/g" | \
kubectl apply -f -
fi
done
done
