Updating an Application

• Console
• CLI
• API

• 1. Sign in to the Console as a functions developer.
  2. Open the navigation menu  and select Developer Services. Under Functions, select Applications.
  3. Select the region you're using with OCI Functions.

     We recommend that you use the same region as the Docker registry that's specified in the Fn Project CLI context. See Creating an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure.

  4. Select the compartment specified in the Fn Project CLI context. See Creating an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure.

     The Applications page shows the applications defined in the compartment.

  5. Select the name of the application that you want to update.

  6. Update some or all the following details:
     • Network security groups: See Adding Applications to Network Security Groups (NSGs)
     • Configuration: See Passing Custom Configuration Parameters to Functions.
     • Signature verification: See Signing Function Images and Enforcing the Use of Signed Images from Registry.
     • Logs: See Storing and Viewing Function Logs.
     • Traces: See Distributed Tracing for Functions.

• Using the Fn Project CLI

  Tip
  
  From time to time, new versions of the Fn Project CLI are released. We recommend you regularly check that the latest version is installed. For more information, see Steps to upgrade the Fn Project CLI.

  To use the Fn Project CLI to update an existing application in the OCI Functions server:

  1. Log in to your development environment as a functions developer.

  2. In a terminal window, update properties of an existing application by entering:

     Command

     CopyTry It

     fn update app <app-name> --<property> <value>

     where:

     • <app-name> is the name of the existing application you want to update.
     • --<property> <value> is the property you want to update, and the new value you want it to have. Enter fn update app --help to see a list of properties and valid values.

     For example:

     Command

     CopyTry It

     fn update app acmeapp --syslog-url tcp://my.papertrail.com:4242

     The properties of the existing application are updated with the values you specified.

  3. Verify that the application has been updated by entering:

     Command

     CopyTry It

     fn inspect app <app-name>

     For example:

     Command

     CopyTry It

     fn inspect app acme-app

     Output:

     {
             "annotations": {
                     "oracle.com/oci/compartmentId": "ocid1.compartment.oc1..aaaaaaaaw______nyq",
                     "oracle.com/oci/subnetIds": [
                             "ocid1.subnet.oc1.iad.aaaaaaaa7______5qa"
                     ]
             },
             "created_at": "2020-02-18T11:53:07.375Z",
             "id": "ocid1.fnapp.oc1.iad.aaaaaaaaaf______r3ca",
             "name": "acme-app",
             "syslog_url": "tcp://my.papertrail.com:4242",
             "updated_at": "2020-03-25T10:13:32.163Z"
     }

  Using the OCI CLI

  Use the oci fn application update command and required parameters to update an application:

  Command

  CopyTry It

  oci fn application update --application-id <application-ocid> [OPTIONS]

  For a complete list of flags and variable options for OCI CLI commands, see the Command Line Reference.

• Run the UpdateApplication API operation to update applications.
