Standalone Airgap Upgrade


This section provides step-by-step instructions for upgrading a standalone Develocity environment without internet access.

Download Required Files

Download K3s

Running the following commands will:

  • Download the K3s binary.

  • Download the K3s airgap image.

  • Download the K3s installation script.

Download the K3s binary:

curl -LO https://github.com/k3s-io/k3s/releases/download/v1.35.2+k3s1/k3s

Download the K3s airgap image:

curl -LO \
  https://github.com/k3s-io/k3s/releases/download/v1.35.2%2Bk3s1/k3s-airgap-images-amd64.tar.gz

Download the K3s installation script:

curl -L -o install_k3s.sh https://get.k3s.io

If you are running Red Hat Enterprise Linux with SELinux enabled, download the K3s policy package:

SELinux policy package download

Lookup the latest version of the K3s SELinux Policy package:

K3S_SELINUX_DOWNLOAD_URL=$(curl -s https://api.github.com/repos/k3s-io/k3s-selinux/releases/latest | jq -r '.assets[] | select( .name | endswith("el8.noarch.rpm") ) | .browser_download_url') && echo $K3S_SELINUX_DOWNLOAD_URL
You can view the versions available and find the download links on the K3s SELinux releases page.

Then download it:

curl -L -o k3s-selinux.el8.noarch.rpm $K3S_SELINUX_DOWNLOAD_URL

Download Helm

Download the Helm binary:

curl -L -o helm-linux-amd64.tar.gz https://get.helm.sh/helm-v4.1.3-linux-amd64.tar.gz

Download Airgap Bundle

Save your Develocity license to the transfer directory as develocity.license.

Download and verify the airgap bundle:

curl -LOJd @develocity.license \
  https://registry.gradle.com/airgap/gradle-enterprise-standalone-2026.1.0-bundle.tar.gz
curl -LOJd @develocity.license \
  https://registry.gradle.com/airgap/gradle-enterprise-standalone-2026.1.0-bundle.tar.gz.sha256
sha256sum -c gradle-enterprise-standalone-2026.1.0-bundle.tar.gz.sha256

If the checksum verification fails, check the contents of the downloaded files for error messages.
If the error message indicates that your license is invalid/expired/not airgap enabled, you will need to request an updated license file by contacting your customer success representative.

Instead of running the above curl commands, you can download the airgap bundle by navigating to https://registry.gradle.com/airgap in your browser and following the instructions on the page.

Transfer Files

Check that the transfer directory has the following files (additional files are fine):

  • k3s-airgap-images-amd64.tar.gz

  • k3s

  • install_k3s.sh

  • k3s-selinux.el8.noarch.rpm (only if you are running SELinux)

  • helm-linux-amd64.tar.gz

  • gradle-enterprise-standalone-2026.1.0-bundle.tar.gz

Once you’ve verified that you have the required files, transfer them to the host where you are installing Develocity.

Import the New Container Images

The new Develocity images must be imported into K3s’s embedded container registry.

Run the following commands to:

  • Unpack the airgap bundle.

  • Import Develocity images into K3s.

tar zxvf gradle-enterprise-standalone-2026.1.0-bundle.tar.gz
sudo k3s ctr images import gradle-enterprise-standalone-2026.1.0-images.tar

Upgrade K3s

Follow these instructions on the host where you install Develocity with your transferred files in the current directory.

If you are running Red Hat Enterprise Linux with SELinux enabled, first install the necessary policy packages:

SELinux Policy installation
Install the k3s-selinux Package

Install the K3s SELinux Policy package you downloaded:

sudo yum install -y k3s-selinux.el8.noarch.rpm

Install K3s and make it available to the current user:

sudo mkdir -p /var/lib/rancher/k3s/agent/images/ && \
  sudo cp k3s-airgap-images-amd64.tar.gz /var/lib/rancher/k3s/agent/images/
(cd /var/lib/rancher/k3s/agent/images/ && sudo gunzip -f k3s-airgap-images-amd64.tar.gz)
sudo cp k3s /usr/local/bin && sudo chmod a+rx /usr/local/bin/k3s
sudo chmod a+rx ./install_k3s.sh && INSTALL_K3S_SKIP_DOWNLOAD=true ./install_k3s.sh
sudo chown $UID /etc/rancher/k3s/k3s.yaml && \
  mkdir -p "${HOME}/.kube" && \
  ln -sf /etc/rancher/k3s/k3s.yaml "${HOME}/.kube/config"

Verify that you can interact with the K3s cluster:

kubectl get namespace
Output
NAME                STATUS   AGE
default             Active   1h
kube-system         Active   1h
kube-public         Active   1h
kube-node-lease     Active   1h
develocity          Active   1h

At this point, you still run the old version of Develocity.
Please confirm it works as expected before proceeding with the upgrade.

Accessing the application and verifying it receives new Build Scan data is the easiest method.

Upgrade Helm

Follow these instructions on the host where you are installing Develocity with your transferred files present in the current directory.

Run the following commands to unpack and install Helm:

tar -zxvf helm-linux-amd64.tar.gz && sudo mv linux-amd64/helm /usr/local/bin/helm

Verify that helm is installed and working:

helm version

Database

It’s strongly recommended to make a database backup before upgrading.

Upgrading Develocity irreversibly changes the database schema.
You will need to restore the database from a backup if you need to roll back the upgrade.

User-Managed Database

For major version upgrades (for example, 2025.4 to 2026.1), if data is stored in a user-managed database and superuser credentials aren’t supplied, the database setup script must be run before the upgrade.

The corresponding scripts can be downloaded via the following links:

Depending on the size of your database, it may take from a few minutes to up to hours.

Upgrade Develocity

Adjust values.yaml Configuration

Adjust your values.yaml configuration file. You can find a detailed list of required changes in the Changes section.

You can discover your current configuration by running the following command:

helm get values \
  --namespace develocity \(1)
  ge-standalone \(2)
  > values.yaml (3)
1 The namespace used to install Develocity.
2 Release name.
3 Output file.

Adjust Unattended Configuration

If you are using unattended configuration, export the current configuration using the Admin UI. Then adjust the exported configuration according to the Changes section.

You can validate your unattended configuration against the schema by using the Develocity command line tool (develocityctl):

develocityctl config-file validate unattended-configuration.yaml

If your unattended configuration is embedded in the values.yaml file, you can validate it with the following command:

cat values.yaml | yq '.global.unattended.configuration' | develocityctl config-file validate -

Unattended configuration is versioned. If an older version is provided, the application migrates the config to the latest version automatically. If you use version control, it’s recommended that you export your unattended configuration after the upgrade and store the latest version in your repository. See Migrating Unattended Configuration for details.

Decide on the Upgrade Command

You may need to run different upgrade commands depending on your configuration changes.

The helm upgrade command is used to upgrade an existing release. It has several flags that control how the values are used for the upgrade. Specifically, the --reuse-values and --reset-values flags modify the behavior around the values passed to the upgrade.

  • --reuse-values: Keeps existing values and allows the setting of additional values.

  • --reset-values: Discards any previously set values and requires all values to be set.

Both flags give you fine-grained control over how values are managed during an upgrade, depending on whether you want to preserve or reset your previous configurations.

For more information about the helm upgrade command, refer to the official Helm documentation.

No Changes

Use case: You want to upgrade but keep all the values from the current deployment without any modifications.

This is useful to ensure that existing values remain unchanged during an upgrade.
This is the most straightforward option if no configuration needs to be modified.

helm upgrade \
  --namespace develocity \(1)
  --reuse-values \(2)
  ge-standalone \(3)
  gradle-enterprise-standalone-2026.1.0.tgz (4)
1 The namespace used to install Develocity
2 Reuse the configuration from the current deployment without any modifications
3 The release name
4 The chart archive

Simple Changes

Use case: You have an existing configuration and want to update the license value and disable ingress SSL, but keep the rest of the configuration.

helm upgrade \
  --namespace develocity \(1)
  --reuse-values \(2)
  --set-file global.license.file=./develocity.license \(3)
  --set ingress.ssl.enabled=false \(4)
  ge-standalone \(5)
  gradle-enterprise-standalone-2026.1.0.tgz (6)
1 The namespace used to install Develocity
2 Reuse the configuration from the current deployment without any modifications
3 The path to the new license file
4 Disable the Ingress SSL
5 The release name
6 The chart archive
This method works correctly only if you add new values or override existing values.
It won’t remove any previously set values, so that you may have a corrupted configuration.

Example:

previously-applied-config.yaml
objectStorage:
  type: s3
  s3:
    bucket: example-bucket
    region: example-aws-region-1
    credentials:
      source: environment
new-config.yaml
objectStorage:
  type: s3
  s3:
    bucket: example-bucket
    region: example-aws-region-1
    credentials:
      type: instanceProfile

Upgrade command:

helm upgrade \
  --namespace develocity \
  --reuse-values \(1)
  --values new-config.yaml \(2)
  ge-standalone \
  gradle-enterprise-standalone-2026.1.0.tgz
1 Reuse the configuration from the current deployment without any modifications
2 Additionally, apply the partial configuration from the new-config.yaml file

You might expect the source: environment to be removed and the type: instanceProfile to be added, but the result is different:

objectStorage:
  type: s3
  s3:
    bucket: example-bucket
    region: example-aws-region-1
    credentials:
      source: environment
      type: instanceProfile

The application throws an error since the old configuration block is no longer supported, but it’s still present.

UPGRADE FAILED: execution error at (gradle-enterprise/templates/enterprise-app/deployment.yaml:3:3):
The `objectStorage.s3.credentials.source` attribute was removed.
Please use `objectStorage.s3.credentials.type instead.
The old attribute isn’t ignored during the upgrade process to quickly detect misconfigurations.

Complex Changes

The --reset-values flag will discard all the values from the previous configuration.

Helm will use the default values defined in the chart during the upgrade, and any custom values previously set (whether through --set, --set-file, --values, or from the original release) will be ignored unless explicitly provided during the upgrade.

Use case: You want to upgrade to Develocity 2026.1 and adjust the Object Storage configuration (see the example above).

helm upgrade \
  --namespace develocity \(1)
  --reset-values \(2)
  --values values.yaml \(3)
  --set-file global.license.file=./develocity.license \(4)
  ge-standalone \(5)
  gradle-enterprise-standalone-2026.1.0.tgz (6)
1 The namespace used to install Develocity
2 Discard old configuration settings
3 The path to the entire configuration file. No settings are preserved from the previous configuration
4 The path to the Develocity license file (if not included in values.yaml)
5 The release name
6 The chart archive

Use dry-run to Verify the Upgrade

Before upgrading, you can use the --dry-run flag to verify the upgrade process.
This will show you the changes that would be made without actually applying them.

For example (if no changes were required):

helm upgrade \
  --namespace develocity \
  --reuse-values \
  ge-standalone \
  gradle-enterprise-standalone-2026.1.0.tgz \
  --dry-run

The actual command may differ depending on the outcome from the previous step.

If the --dry-run command completes successfully, you can proceed with the upgrade.
Otherwise, review the output and make any necessary changes to your configuration.

--dry-run validates syntax, verifies the chart structure, validates your configuration with schema, and checks the generated Kubernetes manifests for errors. However, it won’t detect issues like typos in optional fields or guarantee the application configuration will function correctly.

Execute the Upgrade

Remove --dry-run from the command above and execute the upgrade.

For example (if no changes were required):

helm upgrade \
  --namespace develocity \
  --reuse-values \
  ge-standalone \
  gradle-enterprise-standalone-2026.1.0.tgz

Verify the Upgrade

After executing the upgrade, verify that the Helm release has been updated:

helm list --namespace develocity
Output
NAME            NAMESPACE           REVISION  UPDATED         STATUS    CHART                                  APP VERSION
ge-standalone   develocity          2         2026-03-25      deployed  gradle-enterprise-standalone-2026.1.0  2026.1.0

You can inspect the status of the Develocity Pods:

kubectl get pods --namespace develocity

Wait until all Pods have a status of Running.

Develocity has a /ping endpoint, which can be used to verify that the application is up and running:

curl -sw \\n --fail-with-body --show-error https://«develocity-host»/ping

It should return {"status":"UP"} as response message.
