It does so by checking if any session key on-chain is present on this node. Returns the validator address and the session key if this node is validating. This action does the same as the `update-status` hook does for a validator/collator. However, the `update-status` only shows if the node is validating or not, while this action also gives the validator address and the session key used. * get-node-help Gets the help information from the client binary. Note that to get a readable output it is recommended to use '--format json' and parse the output with the 'jq' command line tool. Example Juju 2.x: juju run-action --wait polkadot/0 get-node-help --format json | jq -r '.["unit-polkadot-0"].results["help-output"]' Example Juju 3.x: juju run polkadot/0 get-node-help --format json | jq -r '.["polkadot/0"].results["help-output"]' * get-node-info Gets system information about the node and its container. * get-session-key Runs author\_rotateKeys and returns a new session-key. * get-session-key-with-owner Runs author\_rotateKeysWithOwner for the supplied owner address and returns a new session-key with ownership proof. Params + address string Owner address used to generate the ownership proof. E.g. address='DuLr6CeLXezrfumF6EkqLeAx9paMcADYU6zHpSZVB8gvjht' Required address * has-session-key Checks if node has a session key, using an RPC call. Params + key string Key to check if exist on node. E.g. key='0xhjd39djk309' Required key * insert-key Inserts a key in the keystore of the node using a local RPC call. WARNING: don't do double signing by inserting the same key for two nodes! Keys are generated using the external tool subkey (not provided by the charm) E.g 'subkey generate --network efinity' Params + address string The public part of the key in hex format. E.g. address='0xf0014b9f4b10ac206a0f3ba9630e1df1f80214e7724e96ab00ccb35d08045777' + mnemonic string The private part of the key as a seed phrase. E.g. mnemonic='reunion learn town satisfy social split ticket improve sunset faculty tail adjust' Required mnemonic, address * is-validating-next-era Checks if this node will be validating next era for the validator address passed as parameter. It does so by checking if the session key that will be used for that validator is present on this node. Returns a message whether this node will be validating next era or not. If it will, the session key is returned as well. Params + address string The public address to check. E.g. DuLr6CeLXezrfumF6EkqLeAx9paMcADYU6zHpSZVB8gvjht Required address * migrate-data Migrate Polkadot data from legacy location to snap common directory Params + dry-run boolean Perform a dry run without actually moving data + reverse boolean Undo the migration by moving data back to the legacy location + snap-name string Name of the snap * migrate-node-key Migrate the node key from legacy location to snap common directory Params + dry-run boolean Perform a dry run without actually moving the node key + reverse boolean Undo the migration by moving the node key back to the legacy location + snap-name string Name of the snap * print-readme Prints the README file for the charm. * restart-node-service This actions restarts the service running the blockchain node. * set-node-key Sets a new private key in the node key file for this Juju application and restarts the node service. A node key can be generated with the external tool subkey (not provided by the charm) E.g. `subkey generate-node-key --file node-key`. The content of node-key is the private key and what should be used for the 'key' parameter. Params + key string Private node key. Required key * snap-refresh Will run snap refresh for the Polkadot snap. NOTE: If the endure config is set to 'true' you will need to restart the service with 'restart-node-service' to make it run with the new version. * start-node-service This actions starts the service running the blockchain node. * start-validating Makes this node start validating. It will use the config parameter 'mnemonic-secret-id' to sign the transaction and therefore start validating for that address. It does so by setting a new session key on-chain. The actual move of the validator might thus take some time to have effect. NOTE: Make sure the wallet is correct and has funds to pay for the transaction, or this will fail. Params + address string Optional! The public address to start validating for. E.g. DuLr6CeLXezrfumF6EkqLeAx9paMcADYU6zHpSZVB8gvjht Only needed if the node should start validating for a different address than the one in the config parameter 'mnemonic-secret-id'. This is typically the case for proxy accounts. I.e. if 'mnemonic-secret-id' is the mnemonic of a proxy account, this parameter should be the address of the validator account. * stop-node-service This actions stops the service running the blockchain node.
