Bitnami has deprecated their free images, see details here: - https://github.com/bitnami/charts/issues/35164 Also dashboard has moved helper images to `bitnamilegacy`, we will fully replace it by our new dashboard soon: - https://github.com/cozystack/cozystack/pull/1269 ### Release note <!-- Write a release note: - Explain what has changed internally and for users. - Start with the same [label] as in the PR title - Follow the guidelines at https://github.com/kubernetes/community/blob/master/contributors/guide/release-notes.md. --> ```release-note Get rid of bitnami images ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * New Features * Added configurable image overrides for Kubeapps components (frontend, auth proxy, Redis, kubectl). * Introduced image settings for Velero’s kubectl helper. * Added image configuration for Vertical Pod Autoscaler components. * Added a configurable resize hook image for SeaweedFS volumes. * Chores * Standardized kubectl-related images to alpine/k8s:1.33.4 across multiple operational hooks (VM update, PVC resize, etcd maintenance, SeaweedFS pre-upgrade), with no behavioral changes. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Virtual Machine (simple)
A Virtual Machine (VM) simulates computer hardware, enabling various operating systems and applications to run in an isolated environment.
Deployment Details
The virtual machine is managed and hosted through KubeVirt, allowing you to harness the benefits of virtualization within your Kubernetes ecosystem.
- Docs: KubeVirt User Guide
- GitHub: KubeVirt Repository
Accessing virtual machine
You can access the virtual machine using the virtctl tool:
To access the serial console:
virtctl console <vm>
To access the VM using VNC:
virtctl vnc <vm>
To SSH into the VM:
virtctl ssh <user>@<vm>

U Series
The U Series is quite neutral and provides resources for general purpose applications.
U is the abbreviation for "Universal", hinting at the universal attitude towards workloads.
VMs of instance types will share physical CPU cores on a time-slice basis with other VMs.
U Series Characteristics
Specific characteristics of this series are:
- Burstable CPU performance - The workload has a baseline compute performance but is permitted to burst beyond this baseline, if excess compute resources are available.
- vCPU-To-Memory Ratio (1:4) - A vCPU-to-Memory ratio of 1:4, for less noise per node.
O Series
The O Series is based on the U Series, with the only difference being that memory is overcommitted.
O is the abbreviation for "Overcommitted".
UO Series Characteristics
Specific characteristics of this series are:
- Burstable CPU performance - The workload has a baseline compute performance but is permitted to burst beyond this baseline, if excess compute resources are available.
- Overcommitted Memory - Memory is over-committed in order to achieve a higher workload density.
- vCPU-To-Memory Ratio (1:4) - A vCPU-to-Memory ratio of 1:4, for less noise per node.
CX Series
The CX Series provides exclusive compute resources for compute intensive applications.
CX is the abbreviation of "Compute Exclusive".
The exclusive resources are given to the compute threads of the VM. In order to ensure this, some additional cores (depending on the number of disks and NICs) will be requested to offload the IO threading from cores dedicated to the workload. In addition, in this series, the NUMA topology of the used cores is provided to the VM.
CX Series Characteristics
Specific characteristics of this series are:
- Hugepages - Hugepages are used in order to improve memory performance.
- Dedicated CPU - Physical cores are exclusively assigned to every vCPU in order to provide fixed and high compute guarantees to the workload.
- Isolated emulator threads - Hypervisor emulator threads are isolated from the vCPUs in order to reduce emaulation related impact on the workload.
- vNUMA - Physical NUMA topology is reflected in the guest in order to optimize guest sided cache utilization.
- vCPU-To-Memory Ratio (1:2) - A vCPU-to-Memory ratio of 1:2.
M Series
The M Series provides resources for memory intensive applications.
M is the abbreviation of "Memory".
M Series Characteristics
Specific characteristics of this series are:
- Hugepages - Hugepages are used in order to improve memory performance.
- Burstable CPU performance - The workload has a baseline compute performance but is permitted to burst beyond this baseline, if excess compute resources are available.
- vCPU-To-Memory Ratio (1:8) - A vCPU-to-Memory ratio of 1:8, for much less noise per node.
RT Series
The RT Series provides resources for realtime applications, like Oslat.
RT is the abbreviation for "realtime".
This series of instance types requires nodes capable of running realtime applications.
RT Series Characteristics
Specific characteristics of this series are:
- Hugepages - Hugepages are used in order to improve memory performance.
- Dedicated CPU - Physical cores are exclusively assigned to every vCPU in order to provide fixed and high compute guarantees to the workload.
- Isolated emulator threads - Hypervisor emulator threads are isolated from the vCPUs in order to reduce emaulation related impact on the workload.
- vCPU-To-Memory Ratio (1:4) - A vCPU-to-Memory ratio of 1:4 starting from the medium size.
