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 being replaced with guance.com.
Introduction¶
This document will guide you through how to replace the domain of Guance. The main steps are as follows:
- Modify the domain in Launcher
- Update all domains in configmaps
- Add certificate Secret (optional)
- Update all ingress domains
- Restart services
Impact Scope¶
Guance Studio will be unavailable for approximately 15-30 minutes.
Operation Steps¶
Step One: Modify Domain and Certificate Name in Launcher¶
- Open the settings in the top-right corner of Launcher.
- Click on Domain.
- Update the domain and save.
Step Two: Update All Domains in Configmaps¶
- 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 update the addresses:
Note
You need to replace the OLD_VALUE and NEW_VALUE variables.
# 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 Domain TLS Certificate".
- Update the TLS certificate and save.
Step Four: Update 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 update the addresses:
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
