Abstract
Methods, systems, and computer program products for container image management are disclosed. In a method, a first group of operations that are performed in respective layers in a base image are obtained. A second group of operations that are performed in respective layers not comprised in the base image are obtained. The second group of operations are optimized based on a comparison between the first and second groups of operations. A destination container image is generated based on the optimized second group of operations and the base image.
Claims17
A method comprising:
- obtaining, by one or more processors, a first group of operations that are performed in respective layers comprised in a base image;
- obtaining, by one or more processors, a second group of operations that are performed in respective layers not comprised in the base image;
- optimizing, by one or more processors, the second group of operations based on a comparison between the first and second groups of operations;
- in response to an operation of the second group of operations being repeated within the first group of operations, classifying, by one or more processors, the operation into a first type or a second type, the first type representing an operation changing the destination container image, and the second type representing an operation not changing the destination container image;
- in response to the operation being classified as the first type, comparing, by one or more processors, the operation with the first group of operations;
- in response to the operation being classified as the second type, deleting, by one or more processors, the operation from the second group;
- and
- generating, by one or more processors, a destination container image based on the optimized second group of operations and the base image.
5 more elements
A computer program product comprising:
- one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
- program instructions to obtain a first group of operations that are performed in respective layers comprised in a base image;
- program instructions to obtain a second group of operations that are performed in respective layers not comprised in the base image;
- program instructions to optimize the second group of operations based on a comparison between the first and second groups of operations;
- program instructions, in response to an operation of the second group of operations being repeated within the first group of operations, to classify the operation into a first type or a second type, the first type representing an operation changing the destination container image, and the second type representing an operation not changing the destination container image;
- program instructions, in response to the operation being classified as the first type, to compare the operation with the first group of operations;
- program instructions, in response to the operation being classified as the second type, to delete the operation from the second group;
- and
- program instructions to generate a destination container image based on the optimized second group of operations and the base image.
6 more elements
A computer system comprising:
- one or more computer processors;
- one or more computer readable storage media;
- and
- program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
- program instructions to obtain a first group of operations that are performed in respective layers comprised in a base image;
- program instructions to obtain a second group of operations that are performed in respective layers not comprised in the base image;
- program instructions to optimize the second group of operations based on a comparison between the first and second groups of operations;
- program instructions, in response to an operation of the second group of operations being repeated within the first group of operations, to classify the operation into a first type or a second type, the first type representing an operation changing the destination container image, and the second type representing an operation not changing the destination container image;
- program instructions, in response to the operation being classified as the first type, to compare the operation with the first group of operations;
- program instructions, in response to the operation being classified as the second type, to delete the operation from the second group;
- and
- program instructions to generate a destination container image based on the optimized second group of operations and the base image.
