Inspect Image

The inspect command reports on the contents of a container image providing version and location information for Java and WebLogic installations.

Usage: imagetool inspect [OPTIONS]
Parameter Definition Default
--image, -i (Required) The image ID or image name to be inspected.
--builder, -b Executable to process the Dockerfile. Use the full path of the executable if not on your path. docker
--format The output format. Supported values: JSON JSON
--patches Include OPatch information in the output, including a list of WebLogic patches that are applied.

Use an argument file

You can save all arguments passed for the Image Tool in a file, then use the file as a parameter.

For example, create a file called build_args:

inspect
--image wls:12.2.1.4.0
--patches

Use the argument file on the command line, as follows:

$ imagetool @/path/to/build_args

Usage scenarios

  • Inspect an image created with the create command where the latest PSU was applied.

    $ imagetool.sh inspect --image example:12214 --patches
    

    The output will be in JSON format and will be similar to:

    {
      "oraclePatches" : [
        {
          "patch" : "xxxxxxx",
          "description" : "WLS PATCH SET UPDATE 12.2.1.4.xxxxxxx"
        }
      ],
      "javaHome" : "/u01/jdk",
      "javaVersion" : "1.8.0_xxx",
      "opatchVersion" : "13.9.4.2.5",
      "oracleHome" : "/u01/oracle",
      "oracleHomeGroup" : "oracle",
      "oracleHomeUser" : "oracle",
      "oracleInstalledProducts" : "WLS,COH,TOPLINK",
      "packageManager" : "YUM",
      "wlsVersion" : "12.2.1.4.0"
    }
    
  • Inspect the same image without the optional --patches switch.

    $ imagetool.sh inspect --image example:12214
    

    The output will be in JSON format and will be similar to:

    {
      "javaHome" : "/u01/jdk",
      "javaVersion" : "1.8.0_xxx",
      "oracleHome" : "/u01/oracle",
      "oracleHomeGroup" : "oracle",
      "oracleHomeUser" : "oracle",
      "oracleInstalledProducts" : "WLS,COH,TOPLINK",
      "packageManager" : "YUM",
      "wlsVersion" : "12.2.1.4.0"
    }
