Ubuntu 20.10: Docker image

Prerequistes

Notice: Subscription is required for business use.

Preparation

(Optional) Fetch Tanzu CLI

cp ../scripts/fetch-tanzu-cli.sh .
./fetch-tanzu-cli.sh {VMWUSER} {VMWPASS} linux {TANZU_CLI_VERSION}

Replace {VMWUSER} and {VMWPASS} with credentials you use to authenticate to https://console.cloud.vmware.com. Replace {TANZU_CLI_VERSION} with a supported (and available) version number for the CLI you wish to embed in the container image. If your account has been granted access, the script will download a tarball, extract the Tanzu CLI and place it into a dist directory. The tarball and other content will be discarded. (The script has "smarts" built-in to determine whether or not to fetch a version of the CLI that may have already been fetched and placed in the dist directory).

(Optional) Fetch and install oci CLI

cp ../scripts/fetch-and-install-oci-cli.sh .

You're just copying this script into place. It will be part of the container image and you'll be able to execute it after a docker run.

Building

If you want to build a portable container image, then execute

docker build -t tanzu/k8s-toolkit .

or

nerdctl build -t tanzu/k8s-toolkit .

Launching

Execute

docker run --rm -it tanzu/k8s-toolkit /bin/bash

or

nerdctl container run --rm -it tanzu/k8s-toolkit /bin/bash

Launching with ability to create TKG cluster

In order to create TKG clusters we need to be able to use docker for the kind bootstrap process. Using the command below will set the network to host allowing the kind cluster's network to be accessible from the container, as well as mounting the docker socket to give access to the underlying host's docker daemon.

docker run -it -v /var/run/docker.sock:/var/run/docker.sock -v ${PWD}:/workspace  --network=host docker.io/tanzu/k8s-toolkit

Inventory

If you want an inventory of all the relevant tools installed

cp ../scripts/inventory.sh .

Then

docker run --rm -v ${PWD}:/root tanzu/k8s-toolkit /bin/bash /root/inventory.sh

or

nerdctl run --rm -v ${PWD}:/root tanzu/k8s-toolkit /bin/bash /root/inventory.sh
