Upgrade Linux infrastructure

Upgrade Linux chaos infrastructure on SaaS or self-managed platform (SMP).

Run the commands on the VM where the Linux chaos infrastructure is installed. The path differs between SaaS and self-managed platform (SMP).

SaaS

1. Fetch INFRA_ID and ACCESS_KEY from the existing config:

   INFRA_ID=$(sed -n 's/^infraID: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)
   ACCESS_KEY=$(sed -n 's/^accessKey: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)

2. Uninstall the current version:

   /etc/linux-chaos-infrastructure/uninstall.sh

3. Install the new version. Get the binary URL from the Linux infrastructure page in the Harness UI, then run:

   sudo https://app.harness.io/public/shared/tools/chaos/linux/1.50.0/install.sh \
     | bash /dev/stdin \
       --infra-id "$INFRA_ID" \
       --access-key "$ACCESS_KEY" \
       --server-url https://<YOUR_IP>/chaos/lserver/api

   Replace 1.50.0 with the target version and <YOUR_IP> with your cluster address.

SMP

1. Raise a Harness support ticket to get the offline-linux-installer tarball.

2. Copy and extract the tarball on the target VM, then cd into the extracted directory.

3. Fetch INFRA_ID and ACCESS_KEY from the existing config:

   INFRA_ID=$(sed -n 's/^infraID: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)
   ACCESS_KEY=$(sed -n 's/^accessKey: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)

4. Uninstall the current version with /etc/linux-chaos-infrastructure/uninstall.sh.

5. Install the new version:

   sudo ./install.sh \
     --infra-id "$INFRA_ID" \
     --access-key "$ACCESS_KEY" \
     --server-url https://<YOUR_IP>/chaos/lserver/api

This same command works in air-gapped environments once the installer is on the VM.
