These images should be listed after language images so they become secondary service containers. CircleCI maintains only one variant for service images. To speed up builds using RAM volume, add the -ram suffix to the end of a service image tag. CircleCI is working on adding next-gen service convenience images. All convenience images have been extended with additional tools, installed with apt-get :.
The legacy CircleCI convenience images are Debian Jessie - or Stretch -based images, however the next-gen images, cimg , extend the official Ubuntu image. For details on the next-gen images, see the Developer Hub. Each image is tracked in its own repository. The following packages are installed via curl or other means. Note: Excluding language image variants and the service image variant , for legacy images CircleCI does not control which tags are used. These tags are chosen and maintained by upstream projects.
Do not assume that a given tag has the same meaning across images! Usage: Add the following under docker: in your config. This guide, as well as the rest of our docs, are open-source and available on GitHub.
We welcome your contributions. Skip to content Docs Toggle navigation. Note: First, we use docker login to authenticate in Docker Hub. If you use a registry other than Docker Hub, refer to the related documentation about how to push images to that registry.
After the image is successfully pushed it is available for use it in your. If you have any questions, head over to our community forum for support from us and other users. This section demonstrates how to build a Ruby container to use on CircleCI. Note: This section assumes you have already used docker login locally. The example starts with the Ruby 2. However, instead of using FROM ruby From the Ruby Docker Hub page, go to the 2.
Notice the environment variables that are used to pull in the proper versions. This will create a Ruby 2. Next, install node modules, awscli , and PostgreSQL 9. Both Dockerfiles use the same base image buildpack-deps:jessie. This is excellent because it is possible to combine them and install Python to get awscli.
Remove the associated files before committing the Docker image to install by using apt. You will need to verify whether your web-server can cope with this trick. Improve this answer.

Please note: You do not actually prevent the browser from caching the image, you only prevent looking at the cached image. Applying proper headers to your image is the best way imho see the solution of lhunath below. Since this way you also fill the cache unnecessarily with images you do not want to cache with the cost of causing less cache space for things you actually do want to be cached. I believe this article explain the reason for such behaviour. I can't disable cache for one image only a specific image from that page?
What is contained in the response is irrelevant. Whether it's image data, HTML data or whatever else. If it didn't work, you probably didn't do it right. Check the HTTP headers on your response to see if they have been correctly assigned. I wish this worked Chrome doesn't have any problems, but Firefox 14 and IE 8 refuse to refresh the images even with the above headers being sent. This would have been so much cleaner solution than adding some arbitrary parameters to the query string.
PawelKrakowiak Note that adding headers won't work for images that are already cached , since the browser doesn't even ask the server about them and therefore will never see the headers. They will work for any image requests made after you added them.
This solution is intended for programmers, not web designers. I thought I would point that out because one cannot just open and image and add headers to an image, unless they themselves are generating the image in a programming language and this seems to be confusing commenters.

Therefore, Docker containers specified to run your jobs cannot directly communicate with containers running in remote docker.
It is not possible to start a service in remote docker and ping it directly from a primary container or to start a primary container that can ping a service in remote docker. A different way to do this is to use another container running in the same network as the target container:. It is not possible to mount a volume from your job space into a container in Remote Docker and vice versa. You may use the docker cp command to transfer files between these two environments.
For example, to start a container in Remote Docker using a config file from your source code:. In the same way, if your application produces some artifacts that need to be stored, you can copy them from Remote Docker:.
