Change node image

To change the image used for bitcoind, CLN or LND:

bitcoind
values:
  - image:
      repository: lightninglabs/bitcoin-core
      tag: 31-alpine
cln
values:
  - image:
      repository: elementsproject/lightningd
      tag: v26.06.1
lnd
values:
  - image:
      repository: lightninglabs/lnd
      tag: v0.21.0-beta

Full example:

network.yaml
repositories:
  - name: scalinglightning
    url: https://scalinglightning.com/charts
releases:
  - name: bitcoind
    namespace: sl
    chart: scalinglightning/bitcoind
    values:
      - image:
          repository: lightninglabs/bitcoin-core
          tag: 31-alpine
  - name: alice
    namespace: sl
    chart: scalinglightning/cln
    values:
      - image:
          repository: elementsproject/lightningd
          tag: v26.06.1
  - name: bob
    namespace: sl
    chart: scalinglightning/lnd

          tag: v0.21.0-beta

Upgrade an existing node​

To update an existing node to a new version you can call the CLI or Library command create again with the same network.yaml file but with the image value updated to the new value.

NOTE: When changing the image repository or tag, a new pod will be created and unless volume was specified in the configuration all data for that node will be lost.

NOTE: If changing bitcoind node to a new version without a volume all other lightning nodes will need to be destroyed and recreated as they will reference a blockchain that nolonger exists.
