Theoretically, official OS base images will be updated when needed, and then other Docker hub images will detect the base update and be rebuilt. #Java security exception jbidwatcher update There is work in this area tools such as watchtower help here.īut this can lead to a false sense of security, because: So, if a bug in a base image is found, and if the vendors work properly, and if you are somehow watching, then you could be protected. Robotamer/citadel: debian:testing (dangerous, because testing is an alias for different distros at different times).wordpress: php:5.6-apache, eventually depends on debian:jessie.node: buildpack-deps:jessie, eventually depends on debian:jessie.mongo: debian:wheezy-slim (previous release).nginx: debian:stretch-slim (stretch is pre-release at this date!).Consider just these official images, and the bases they use: (tracking latest tag on each) Problem #2: Diverse and complicated vendor security pictureĭifferent images can use different operating system bases. The good news is that Debian jessie seems to be pretty popular here. The bad news is that you see everything from Oracle Linux, to Ubuntu, to Debian testing, to Debian oldstable in just this list. Here s the question: what do you know about the security practices of each of these organizations? How well updated are their base images? Even if it s Debian, how well updated is, for instance, the oldstable or the testing image? Go a little further, and you ll see Alpine Linux, CentOS, and many more represented. Problem #3: No way to detect when intermediate libraries need to be updated The attack surface here is a lot larger than if you were just using a single OS. Let s say your Docker image is using a base that is updated immediately when a security problem is found. Let s further assume that your software package (WordPress, MySQL, whatever) is also being updated. #Java security exception jbidwatcher software What about the intermediate dependencies? Let s look at the build process for nginx. The Dockerfile for it begins with Debian:stretch-slim. #Java security exception jbidwatcher softwareīut then it does a natural thing: it runs an apt-get install, pulling in packages from both Debian and an nginx repo.#Java security exception jbidwatcher update.Services need your login info in order to submit a bid for you.
