Install Verrazzano in a Disconnected Environment
If you are running in a disconnected environment (without access to the Internet), then you will need to install Verrazzano using a private container registry. However, you may choose to install Verrazzano using a private registry even if you are not running in a disconnected environment.
Prerequisites
- You will need to connect to the Internet to download the Verrazzano images and Verrazzano distribution.
- You will need a way to transfer the images to your private registry and the distribution to the disconnected environment.
- Your workstation must have at least 20 GB of disk space.
- You must have the following software installed:
Installing Verrazzano using a private Docker-compliant container registry requires the following:
- Loading all the required Verrazzano container images into your own registry and repositories.
- Installing Verrazzano with the private registry and a common prefix for all the repositories used to load the images.
Get Verrazzano
You can download Verrazzano from the Verrazzano GitHub releases page. Oracle customers also can get Verrazzano from the Oracle Software Delivery Cloud. Follow the respective download instructions:
NOTE: You will need to connect to the Internet to download the Verrazzano images and Verrazzano distribution.
From GitHub
-
Download the desired Verrazzano distribution from the GitHub releases page.
a. In your browser, go to Verrazzano releases.
b. Download the distribution TAR file,
verrazzano-<major>.<minor>.<patch>-<operating system>-<architecture>.tar.gz
, and the corresponding checksum file.c. In the downloaded directory, validate that the checksum and TAR files match. For example, if you have downloaded
verrazzano-1.5.7-linux-amd64.tar.gz
:$ sha256sum -c verrazzano-1.5.7-linux-amd64.tar.gz.sha256 # Sample output verrazzano-1.5.7-linux-amd64.tar.gz: OK
sha256sum
command on Linux andshasum
on MacOS.d. Expand the TAR file to access the release artifacts.
The following example, extracts the distribution archive
verrazzano-1.5.7-linux-amd64.tar.gz
into the current directory.$ tar xvf verrazzano-1.5.7-linux-amd64.tar.gz
verrazzano-1.5.7
directory.e. Define an environment variable
DISTRIBUTION_DIR
.$ DISTRIBUTION_DIR=<path to the current directory>/verrazzano-1.5.7
-
Download the Verrazzano images defined in the BOM,
${DISTRIBUTION_DIR}/manifests/verrazzano-bom.json
, using the script,${DISTRIBUTION_DIR}/bin/vz-registry-image-helper.sh
.$ sh ${DISTRIBUTION_DIR}/bin/vz-registry-image-helper.sh \ -b ${DISTRIBUTION_DIR}/manifests/verrazzano-bom.json \ -f ${DISTRIBUTION_DIR}/images
The previous command downloads all the images to the
${DISTRIBUTION_DIR}/images
directory.
From the Oracle Software Delivery Cloud
-
Download the Verrazzano ZIP file.
-
Download the Verrazzano ZIP file from the Oracle Software Delivery Cloud for major or minor releases.
a. In your browser, go to the Oracle Software Delivery Cloud and log in with your credentials.
b. In the drop-down menu preceding the search bar, select All Categories.
c. In the search bar, enter
Verrazzano Enterprise Container Platform
and click Search.d. Select the
REL: Verrazzano Enterprise Container Platform 1.5.0.0.0
link. This will add it to your download queue.e. At the top of the page, select the Continue link.
f. Review the Download Queue, then click Continue.
g. Accept the license agreement and click Continue.
h. Download the file:
- To download the ZIP file directly, select the file link in the list.
- To download the ZIP file using
Oracle Download Manager
, click Download and run theOracle Download Manager
executable.
-
Download the Verrazzano ZIP file from My Oracle Support for cumulative patches.
a. In your browser, go to My Oracle Support and log in with your credentials.
b. Select the
Patches & Updates
tab.c. In the
Patch Search
panel, select the linkProduct or Family (Advanced)
.d. In the search bar for
Product is
, enterOracle Verrazzano Enterprise Container Platform
.e. The previous step populates the available releases for Verrazzano in the drop-down menu
Release is
. Select the desired release(s) and click Search.f. A new panel with
Patch Advanced Search Results
will open listing all the patches for the release. Select the link for the desired patch, under thePatch Name
.g. From the page providing details about the patch, click Download.
h. Download the ZIP file by selecting the file link.
-
-
Prepare to do the private registry installation.
a. Extract the ZIP archive to a desired directory location. There will be two files: a compressed TAR file containing the product files and a checksum file.
b. Define an environment variable
DISTRIBUTION_DIR
.$ DISTRIBUTION_DIR=<path to the current directory>/verrazzano-1.5.7
c. In the expanded archive directory, validate that the checksum and TAR files match. For example,
$ sha256sum -c verrazzano-1.5.7.tar.gz.sha256 # Sample output verrazzano-1.5.7.tar.gz: OK
NOTE: Use the
sha256sum
command on Linux andshasum
on MacOS.
Load the images
Load the product images into your private registry.
NOTE: You will need a way to transfer the images to your private registry and the distribution to the disconnected environment.
-
To log in to the Docker registry, run
docker login <SERVER>
with your credentials. -
For use with the examples in this document, define the following variables with respect to your target registry and repository:
MYREG
,MYREPO
,VPO_IMAGE
.These identify the target Docker registry and repository, and the Verrazzano platform operator image, as defined in the BOM file. For example, using a target registry of
myreg.io
and a target repository ofmyrepo/v8o
:$ MYREG=myreg.io $ MYREPO=myrepo/v8o $ VPO_IMAGE=$(cat ${DISTRIBUTION_DIR}/manifests/verrazzano-bom.json \ | jq -r '.components[].subcomponents[] | select(.name == "verrazzano-platform-operator") | "\(.repository)/\(.images[].image):\(.images[].tag)"')
-
Run the
${DISTRIBUTION_DIR}/bin/vz-registry-image-helper.sh
script to push the images to the registry:$ sh ${DISTRIBUTION_DIR}/bin/vz-registry-image-helper.sh \ -t $MYREG -r $MYREPO -l ${DISTRIBUTION_DIR}/images
-
Although most images can be protected using credentials stored in an image pull secret, some images must be public. Use the following commands to get the list of public images:
-
The Rancher Agent image.
$ cat ${DISTRIBUTION_DIR}/manifests/verrazzano-bom.json \ | jq -r '.components[].subcomponents[] | select(.name == "rancher") | .images[] | select(.image == "rancher-agent") | "\(.image):\(.tag)"'
-
All the Rancher images in the
rancher/additional-rancher
subcomponent.$ cat ${DISTRIBUTION_DIR}/manifests/verrazzano-bom.json \ | jq -r '.components[].subcomponents[] | select(.name == "additional-rancher") | .images[] | "\(.image):\(.tag)"'
-
The Verrazzano platform operator image identified by
$VPO_IMAGE
, as defined previously in Step 2. -
For all the Verrazzano Docker images in the private registry that are not explicitly marked public, you will need to create the secret
verrazzano-container-registry
in thedefault
namespace, with the appropriate credentials for the registry, identified by$MYREG
.
For example:$ kubectl create secret docker-registry verrazzano-container-registry \ --docker-server=$MYREG --docker-username=myreguser \ --docker-password=xxxxxxxx --docker-email=me@example.com
-
Install Verrazzano
-
Install the Verrazzano platform operator using the image defined by
$MYREG/$MYREPO/$VPO_IMAGE
.
$ helm template --include-crds ${DISTRIBUTION_DIR}/manifests/charts/verrazzano-platform-operator \ --set image=${MYREG}/${MYREPO}/${VPO_IMAGE} --set global.registry=${MYREG} \ --set global.repository=${MYREPO} --set global.imagePullSecrets={verrazzano-container-registry} | kubectl apply -f -
-
Wait for the deployment of the Verrazzano platform operator.
$ kubectl -n verrazzano-install rollout status deployment/verrazzano-platform-operator # Sample output deployment "verrazzano-platform-operator" successfully rolled out
-
Confirm that the Verrazzano platform operator pod is running.
$ kubectl -n verrazzano-install get pods # Sample output NAME READY STATUS RESTARTS AGE verrazzano-platform-operator-74f4547555-s76r2 1/1 Running 0 114s
The distribution archive includes the supported installation profiles under ${DISTRIBUTION_DIR}/manifests/profiles
.
Verrazzano supports customizing installation configurations. See Modify Verrazzano Installations.
To create a Verrazzano installation using the provided profiles, run the following command:
$ kubectl apply -f $DISTRIBUTION_DIR/manifests/profiles/prod.yaml
