Dockerfile ARGs

21 Dockerfile ARGs

Images containing TimesTen and its prerequisites are available at container-registry.oracle.com. You can use these images as is with the TimesTen Kubernetes Operator. You also have the choice to build your own TimesTen container image by using the Dockerfile provided in the /image directory of the operator.zip distribution. The operator.zip distribution is located in the /kubernetes directory of the TimesTen distribution. See Unpack the TimesTen and the TimesTen Operator Distributions.

The Dockerfile supports a number of ARGs. These ARGs let you override the attributes of the Dockerfile (and its resultant image). You supply these ARGs on the docker build command line.

Table 21-1 describes the supported ARGs:
