docker version
$ docker -v Docker version 19.03.2, build 6a30dfc[!TIP] One way to upgrade an image from image manifest version 2, schema 1 to schema 2 is to
docker pullthe image and thendocker pushthe image with a current version of Docker. Doing so will automatically convert the image to use the latest image manifest specification. Converting an image to image manifest version 2, schema 2 converts the manifest format, but does not update the contents within the image. Images using manifest version 2, schema 1 may contain unpatched vulnerabilities. We recommend looking for an alternative image or rebuilding it.
