Command: deployment unblock

The deployment unblock command is used to manually mark a blocked multiregion deployment as successful. A blocked deployment is a multiregion deployment within a region that has completed within a region but is waiting on the other federated regions. The deployment unblock command can be used in cases where a failed peer region is unable to communicate its failed deployment status to other regions to force a deployment to complete.

Usage

nomad deployment unblock [options] <deployment id>

The deployment unblock command requires a single argument, a deployment ID or prefix.

When ACLs are enabled, this command requires a token with the submit-job and read-job capabilities for the deployment's namespace.

General Options

  • -address=<addr>: The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Defaults to http://127.0.0.1:4646.

  • -region=<region>: The region of the Nomad server to forward commands to. Overrides the NOMAD_REGION environment variable if set. Defaults to the Agent's local region.

  • -namespace=<namespace>: The target namespace for queries and actions bound to a namespace. Overrides the NOMAD_NAMESPACE environment variable if set. If set to '*', subcommands which support this functionality query all namespaces authorized to user. Defaults to the "default" namespace.

  • -no-color: Disables colored command output. Alternatively, NOMAD_CLI_NO_COLOR may be set. This option takes precedence over -force-color.

  • -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively, NOMAD_CLI_FORCE_COLOR may be set. This option has no effect if -no-color is also used.

  • -ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the NOMAD_CACERT environment variable if set.

  • -ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both -ca-cert and -ca-path are specified, -ca-cert is used. Overrides the NOMAD_CAPATH environment variable if set.

  • -client-cert=<path>: Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify -client-key. Overrides the NOMAD_CLIENT_CERT environment variable if set.

  • -client-key=<path>: Path to an unencrypted PEM encoded private key matching the client certificate from -client-cert. Overrides the NOMAD_CLIENT_KEY environment variable if set.

  • -tls-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the NOMAD_TLS_SERVER_NAME environment variable if set.

  • -tls-skip-verify: Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if NOMAD_SKIP_VERIFY is set.

  • -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the NOMAD_TOKEN environment variable if set.

Unblock Options

  • -detach: Return immediately instead of monitoring. A new evaluation ID will be output, which can be used to examine the evaluation using the eval status command.

  • -verbose: Show full information.

Examples

Manually mark an ongoing deployment as unblocked. The deployment status shows an error on the unreachable "east" region.

$ nomad deployment unblock 8990cfbc
Deployment "8990cfbc-28c0-cb28-ca31-856cf691b987" unblocked

==> Monitoring evaluation "a2d97ad5"
    Evaluation triggered by job "example"
    Evaluation within deployment: "8990cfbc"
    Evaluation status changed: "pending" -> "complete"
==> Evaluation "a2d97ad5" finished with status "complete"

$ nomad deployment status 8990cfbc
ID          = 8990cfbc
Job ID      = example
Job Version = 2
Status      = successful
Description = Deployment successful
