How to find the docker image versions?

[Boyce Developer]

I'm new to Bitbucket Pipelines. Using some guides to configure them but what I realized is that the images are outdated from when the guides were written.

I keep trying to search where I can find the latest image but there's no documentation I can find that lists the releases for the images.

Can someone guide me on where I can find the versions I can use?

For example, "image: microsoft/dotnet:latest" image didn't support 3.1. I couldn't figure out which image did until I found online of another pipeline configuration that had " image: mcr.microsoft.com/dotnet/core/sdk:3.1". Using that worked luckily.

Same issue with node image as well. Had "image: node:10.15.0" before but I needed a new one. Couldn't figure out what are the newer version until I randomly searched and came across someone using "image: node:12".

Is there like a library or documentation that maintains the version history of the images that can be used in Bitbucket Pipeline?

Most images come from Docker Hub (https://hub.docker.com/) and have the detailed description there:

• https://hub.docker.com/_/microsoft-dotnet-core
• https://hub.docker.com/_/node

Read about the details there as each image can be individual. What you also find there is the list of all tags (the part after the colon) which often show the version. The special tag latest is often updated to the latest version.

So all docker images will be available in the pipeline for use?

Yes in short, this is a longer variant:

We support public and private Docker images including those hosted on Docker Hub, AWS, GCP, Azure and self-hosted registries accessible on the internet. (Bitbucket Pipelines cannot currently access Docker images that cannot be accessed via the internet.)
