Configuring a private repository (YAML)
Turbonomic gathers information from your clusters through the Kubeturbo
container images that are available through a public repository in IBM
Container Registry (icr.io
).
The following list describes the different Kubeturbo container images.
-
Container image for Kubeturbo
This is the primary image and is pulled from
icr.io/cpopen/turbonomic/kubeturbo:<version>
. -
Container image for the CPU frequency getter job
The
cpufreqgetter
image (also known as BusyBox) runs a job on every node to collect CPU speed. This image is pulled fromicr.io/cpopen/turbonomic/cpufreqgetter
.For more information about the parameters associated with this job, see this topic.
If you are using a private repository, be aware that IBM Container
Registry provides multi-architecture container images. Your private repository needs to
support loading these images. For example, multi-architecture container images are supported
in Artifactory version 7.2+, but not in Artifactory version 6. Optionally, pull only the
architecture version that you need. Specify the --platform
parameter with
docker pull
and use docker inspect
to confirm the
architecture.
docker pull --platform linux/arm64 icr.io/cpopen/turbonomic/kubeturbo:8.14.4
docker inspect 49a61c21c3a1 | grep architecture
"architecture": "aarch64",
To use a private repository, you need to define additional parameters in the
deployment
resource, as shown in the following example:
kind: Deployment
metadata:
name: kubeturbo
namespace: turbo
spec:
replicas: 1
selector:
matchLabels:
app.kubernetes.io/name: kubeturbo
template:
spec:
containers:
- name: kubeturbo
image: {your_kubeturbo_repository}/icr.io/cpopen/turbonomic/kubeturbo:8.14.4
args:
- --turboconfig=/etc/kubeturbo/turbo.config
- --v=2
- --kubelet-https=true
- --kubelet-port=10250
- --cpufreqgetter-image={your_frequency_getter_repository}/icr.io/cpopen/turbonomic/cpufreqgetter
# If using busybox parameter, uncomment to override default, and specify your own location
#- --busybox-image=docker.io/busybox
# or uncomment the following to pull from RHCC
#- --busybox-image=registry.access.redhat.com/ubi8/ubi-minimal
# Uncomment to specify the secret name which holds the credentials to busybox OR cprfreqgetter image
#- --busybox-image-pull-secret=<secret-name>
Update the sample command with the following parameters:
-
image: {your_kubeturbo_repository}/icr.io/cpopen/turbonomic/kubeturbo
Specify your private Kubeturbo repository, such as
myrepo.com
. -
--cpufreqgetter-image={your_frequency_getter_repository}/icr.io/cpopen/turbonomic/cpufreqgetter
Specify your private CPU frequency getter repository, such as
mygetterrepo.com
.
