Setting up InfluxDB Database Server with Podman

First create a pod and inflluxdb container using podman, then generate a YAML file using podman play.

The YAML file can be used to recreate the pod in podman, or in kubernetes.

Create a pod​

podman pod create -p 8086:8086 -p 1883:1883 -p 9001:9001 -n monitoring

Pull influxdb image​

podman pull docker.io/influxdb:latest

Run image in pod​

podman run -d -t \
--name influxdb \
--pod monitoring \
influxdb:latest

Pull mosquitto image​

podman pull docker.io/eclipse-mosquitto

Run image in pod​

podman run -t \
--name mosquitto \
--pod monitoring \
eclipse-mosquitto

Generate YAML file​

podman generate kube monitoring -f monitoring-stack.yaml

Here's the YAML file​

# Save the output of this file and use kubectl create -f to import
# it into Kubernetes.
#

Test YAML file​

Delete containers

podman rm -vf influxdb
podman rm -vf mosquitto

Delete pod

podman pod rm monitoring

Re-build pod using podman play and YAML file.

podman play kube monitoring-stack.yaml

Reference​

Oracle-Base

To do​

  • mosquitto configuration
  • influxdb directory
