Feel free to read through the [Tempo HA documentation](https://discourse.charmhub.io/t/charmed-tempo-ha/15531) at your leisure to explore its deployment and its integrations.
To make the Charmed MySQL K8s database reachable from outside the Kubernetes cluster, this charm MySQL Router K8s should be deployed. It creates and manages several K8s services including the NodePort one:
4
+
5
+
```shell
6
+
kubectl get services -n <model>
7
+
```
8
+
9
+
```
10
+
TODO
11
+
```
12
+
13
+
The `TODO` NodePort service exposes a port to access both R/W and R/O MySQL servers from outside of K8s. The charm opens NodePort if requested in relation as `external-node-connectivity: true`. Example (relate mysql-router-k8s with data-integrator):
14
+
```shell
15
+
> juju run data-integrator/0 get-credentials
16
+
...
17
+
TODO
18
+
```
19
+
> **Note**: the relation flag `external-node-connectivity` is experimental and will be replaced in the future. Follow https://warthogs.atlassian.net/browse/DPE-5636 for more details.
20
+
21
+
> **Note**: The `mysql-router-k8s` and `mysql-router-k8s-endpoints` ClusterIP services seen above are created for every Juju application by default as part of the StatefulSet they are associated with. These services are not relevant to users and can be safely ignored.
22
+
23
+
## Client connections using the bootstrap service
24
+
25
+
A client can be configured to connect to the `TODO` service using a Kubernetes NodeIP, and desired NodePort.
26
+
27
+
To get NodeIPs:
28
+
29
+
```shell
30
+
kubectl get nodes -o wide -n model | awk -v OFS='\t\t''{print $1, $6}'
31
+
```
32
+
33
+
```
34
+
NAME INTERNAL-IP
35
+
node-0 10.155.67.110
36
+
node-1 10.155.67.120
37
+
node-2 10.155.67.130
38
+
```
39
+
40
+
NodeIPs are different for each deployment as they are randomly allocated.
41
+
For the example from the previous section, the created NodePorts was:
42
+
43
+
```shell
44
+
TODO
45
+
```
46
+
47
+
Users can use this NodePort to access read-write / Primary server from outside of K8s:
48
+
```shell
49
+
TODO
50
+
```
51
+
Read-only servers can be accessed using the `_readonly` suffix to the desired DB name:
