 | container | boolean | 3.1-M1 | If set to `true`, run the server in the container specified by the `containerfile` parameter. Setting this to `true` and using the `libertyDev` task is equivalent to using the `libertyDevc` task. The default value is `false` when the `libertyDev` task is used, and `true` when the `libertyDevc` task is used. | No |
 | containerRunOpts | String | 3.7 | Specifies options to add to the container `run` command when using dev mode to launch your server in a container. For example, `-e key=value` is recognized by `docker run` to define an environment variable with the name `key` and value `value`. This attribute replaces the deprecated `dockerRunOpts` attribute. | No |
 | containerfile | File | 3.7 | Location of a Containerfile or Dockerfile to be used by dev mode to build the image for the container that will run your Liberty server. The default location is `Containerfile` or `Dockerfile` in the project root. This attribute replaces the deprecated `dockerfile` attribute. | No |
-| cotnainerBuildContext | File | 3.7 | The container build context directory to be used by dev mode for the container `build` command.  The default location is the directory of the Containerfile/Dockerfile. This attribute replaces the deprecated `dockerBuildContext` attribute. | No |
+| containerBuildContext | File | 3.7 | The container build context directory to be used by dev mode for the container `build` command.  The default location is the directory of the Containerfile/Dockerfile. This attribute replaces the deprecated `dockerBuildContext` attribute. | No |
 | containerBuildTimeout | integer | 3.7 | Maximum time to wait (in seconds) for the completion of the container operation to build the image. The value must be an integer greater than 0. The default value is `600` seconds. This attribute replaces the deprecated `dockerBuildTimeout` attribute. | No |
 | skipDefaultPorts | boolean | 3.1-M3 | If set to `true`, dev mode will not publish the default container port mappings of `9080:9080` (HTTP) and `9443:9443` (HTTPS). Use this option if you would like to specify alternative local ports to map to the exposed container ports for HTTP and HTTPS using the `containerRunOpts` parameter. | No |
 | keepTempContainerfile | boolean | 3.7 | If set to `true`, dev mode will not delete the temporary modified copy of your Containerfile/Dockerfile used to build the container image. This file is handy in case you need to debug the process of building the container image. The path of the temporary Containerfile/Dockerfile can be seen when dev mode displays the container `build` command. The default value is `false`. This attribute replaces the deprecated `keepTempDockerfile` attribute. | No |
