Downloading file from aws dockerfile

The uncompression feature is described in the official documentation as follows:. This means that your final outcome depends on the contents of the file you intend to copy, and you don't get warnings if something goes wrong. This may make your build pipeline unpredictable.

COPY does one thing and it does it well. In real-life projects COPY is sufficient in most scenarios , mainly because we rarely add tarballs to our applications' source code. The main use-case for tarballs, thus ADD , is when we create a base image from a tar archive. Ankita Dhandha Ankita Dhandha 2 2 silver badges 9 9 bronze badges. That's all good for a file that never change.

But if you're expecting to always copy the latest version then you're in for troubles as docker can use the layer it has in its cache!

The Dockerfile reference warns about using ARG and passing --build-args for secrets, because the values appear in the history: docs. Anyway to circumvent this?

No i am afraid history does pass back those args.. I guess the question is if they have access to that could they get the secrets anyway? If it is a huge issue look at suggestion 2 i said or maybe something like this could help - docs. I wanted to build upon Ankita Dhandha answer. In the case of Docker you are probably looking to use ECS.

IAM Roles are absolutely the way to go. An example would be having access to S3 to download ecs. Task Roles are used for a running container. An example would be a live web app that is moving files in and out of S3.

Task Execution Roles are for deploying the task. An example would be downloading the ECR image and deploying it to ECS, downloading an environment file from S3 and exporting it to the Docker container. Not everything behaves like this. But many do so you have to research it for your situation. Task Execution Role used to deploy the docker task. The running task will use the Task Role.

When the running task has no permissions for the current action it will attempt to elevate into the EC2 instance role. Unlimited Support Plan. Chat Support for Admin. Separate Account Manager. SLA Review Meetings. Simple SignUp Process. Instant Account Activation.
