SPK Software¶

Overview¶

The Service Proxy for Kubernetes (SPK) custom resource definitions (CRDs), software images and installation Helm charts are provided in a single TAR file. An SPK public signing key, and two signature files are also provided to validate the TAR file’s integrity. Once validated and extracted, the software images can be uploaded to a local container registry, and integrated into the cluster using the SPK Helm charts. Finally, the SPK CRDs will be installed into the cluster.

This document describes the SPK software, and guides you through validating, extracting and installing the SPK software components.

Software images¶

The table below lists and describes the software images for this software release. For a full list of software images by release, refer to the Software Releases guide.

f5-spk-crds-deprecated.7.0.4.tgz

A bundle containing the deprecated CRDs, beginning with SPK software version 1.4.3.

Requirements¶

Ensure you have:

Obtained the SPK software tarball.
A local container registry.
A workstation with Podman and OpenSSL.

Procedures¶

Extract the images¶

Use the following steps to validate the SPK tarball, and extract the software images, installation Helm charts, and CRDs.

Create a new directory for the SPK files:
```
mkdir <directory>
```
In this example, the new directory is named spkinstall:
```
mkdir spkinstall
```

Move the SPK files into the directory:

mv f5-spk-tarball* f5-spk-1.8.pem spkinstall

Change into the directory and list the files:

cd spkinstall; ls -1

The file list appears as:

f5-spk-1.8.pem
f5-spk-tarball-1.8.tgz
f5-spk-tarball-sha512.txt-1.8.sha512.sig
f5-spk-tarball.tgz-1.8.sha512.sig

Use the PEM signing key and each SHA signature file to validate the SPK TAR file:

openssl dgst -verify <pem file>.pem -keyform PEM \
-sha512 -signature <sig file>.sig <tar file>.tgz

The command output states Verified OK for each signature file:

openssl dgst -verify f5-spk-1.8.pem -keyform PEM -sha512 \
-signature f5-spk-tarball.tgz-1.8.sha512.sig \
f5-spk-tarball-1.8.tgz

Verified OK

openssl dgst -verify f5-spk-1.8.pem -keyform PEM -sha512 \
-signature f5-spk-tarball-sha512.txt-1.8.sha512.sig \
f5-spk-tarball-1.8.tgz

Verified OK

Extract the SPK CRD bundles and the software image TAR file:
```
tar xvf f5-spk-tarball-1.8.tgz
```

List the newly extracted files:

ls -1

The file list shows the CRD bundless and the SPK image TAR file named f5-spk-images-1.8.tgz:

f5-spk-1.8.pem
f5-spk-crds-common-7.0.4.tgz
f5-spk-crds-deprecated-7.0.4.tgz
f5-spk-crds-service-proxy-7.0.4.tgz
f5-spk-images-1.8.tgz
f5-spk-tarball-1.8.tgz
f5-spk-tarball-sha512.txt-1.8.sha512.sig
f5-spk-tarball.tgz-1.8.sha512.sig

Extract the SPK software images and Helm charts:
```
tar xvf f5-spk-images-1.8.tgz
```

Recursively list the extracted software images and Helm charts:

ls -1R

The file list shows a new tar directory containing the software images and Helm charts:

f5-spk-1.8.pem
f5-spk-crds-common-7.0.4.tgz
f5-spk-crds-deprecated-7.0.4.tgz
f5-spk-crds-service-proxy-7.0.4.tgz

f5-spk-tarball-1.8.tgz
f5-spk-tarball-sha512.txt-1.8.sha512.sig
f5-spk-tarball.tgz-1.8.sha512.sig
tar

./tar:
csrc-0.4.0.tgz
cwc-4.0.8.tgz
f5-cert-gen-0.7.3.tgz
f5-cert-manager-0.5.16.tgz
f5-crdconversion-0.3.8.tgz

Continue to the next section.

Install the CRDs¶

Use the following steps to extract and install the new SPK CRDs.

List the SPK CRD bundles:

ls -1 | grep crd

The file list shows three CRD bundles:

f5-spk-crds-common-7.0.4.tgz
f5-spk-crds-deprecated-7.0.4.tgz
f5-spk-crds-service-proxy-7.0.4.tgz

Extract the common CRDs from the bundle:
```
tar xvf f5-spk-crds-common-7.0.4.tgz
```

Install the full set of common CRDs:

oc apply -f f5-spk-crds-common/crds

Note the command output: Newly installed CRDs will be indicated by created, and updated CRDs will be indicated by configured:

Upload the images¶

Use the following steps to upload the SPK software images to a local container registry.

Install the SPK images to your workstation’s Docker image store:
```
podman load -i tar/spk-docker-images.tgz
```

List the SPK images to be tagged and pushed to the local container registry in the next step:

podman images --format "table {{.Repository}} {{.Tag}} {{.ID}}"

Tag and push each image to the local container registry. For example:

podman tag <local.registry/image name>:<version> <registry>/<image name>:<version>

podman push <registry_name>/<image name>:<version>

In this example, the f5ingress:v11.0.23 image is tagged and pushed to the remote registry registry.com:

podman tag local.registry/f5ingress:v11.0.23 registry.com/f5ingress:v11.0.23

podman push registry.com/f5ingress:v11.0.23

Once all of the images have uploaded, verify the images exist in the local container registry:

curl -X GET https://<registry>/v2/_catalog -u <user:pass>

For example:

curl -X GET https://registry.com/v2/_catalog -u spkadmin:spkadmin

"repositories":["f5-debug-sidecar","f5-dssm-store","f5-fluentbit","f5-fluentd","f5-toda-tmstatsd","f5dr-img","f5ingress","tmm-img","tmrouted-img"]}
