The following technique can reduce the time in general. While this makes use of caching, it needs to be re-executed from scratch every time

#Docker for mac kubernetes mount local volume install#

RUN pip install -r /src/requirements.txt #only re-executed if the file changes single time.ĪDD code/requirements.txt /src/requirements.txt RUN pip install -r /src/code/requirements.txt #this will run every. By adding your dependency definition file first,Īnd installing them before you add your complete code, you’ll be able to skip this expensive step If you install your dependencies after adding your codebase, youĭon’t make use of the caching which Docker provides.

You can apply this, if you have something like a requirements.txt file, which describes third-party You can read more about this approach,Īpplied to building an image for a Python application - you can read more on that here. You could make the dependency-installing step less frequent, by adding the dependencyĭefinition file before you add all your code. Only Install Dependencies If They Actually Change Going to be huge due to all the diff layers, and only use the results by issuing a COPY -from command Result, you could use this technique to do the heavy lifting in an intermediate image, accept that it’s If you’re working with a tar ball of data, need to unpack it to process it, but are only interested in the # finally, /result ends up with the final data Here is an example multi-stage Dockerfile: FROM ubuntu as intermediate If you’re just looking to reduce the final size of your image - take a look at multi-stage builds.

  • COPY data into your image, without relying on host-specific operations, thus providing a better place to start than from-scratch.
  • Make the cache-dependent operation less frequent (given that your dependencies areĬhanging less frequently than your complete codebase),.
  • Get messy operation out of your main Docker image, and only use the results,.
  • Although you can’t have volumes, you can get the benefits withĪ bit of one-time effort, and at the cost of slightly higher complexity. Going to take another 10 minutes after the fix, doesn’t it? Image from your Dockerfile? Even if it’s on the same CI server, the data is right there and oh no, it’s So, do you have to accept that your image is 1.5GB larger than it should be?ĭo you really have to watch your build process start from scratch every. It would be really handy - if you use a volume, you’re not impacting the size of the image,Ĭan mount data from outside of the container and reuse previously executed work as a kind-of-starting-point. Right now, you can’t mount volumes, as you can when working with containers.
