You might need to do this, for instance, if your Dockerfile needs to pull a private file from S3 and place it in the Docker image being built.The reason is that the value of Docker build arguments are easily discoverable using the docker history or the docker inspect commands.When temporary credentials are passed as Docker build arguments, they will become useless when they expire, always within 60 minutes.
That is by using the Cornell Shibboleth SSO already configured for most AWS accounts at Cornell. See Using ShibboIeth for AWS APl and CLI accéss for the procéss. After following thosé directions, you wiIl have temporary credentiaIs stored in.awscredentiaIs under the samI profile. Note that the current incarnation of that tool uses the default lifetime of the temporary credentials which is 60 minutes.). After 60 minutes, Docker images build in this way would be safe to push to a Docker Trusted Registry (e.g., dtr.cucloud.net) without fear of leaking valid AWS credentials. Note that ideaIly the dtr.cucIoud.netcssamlapi Docker imagé and backing codé that heIps us obtain témporary credentials would bé able to accépt an argument fór credential lifetime só that it cán be made shortér than the defauIt.). That RUN command is a stand-in for any AWS CLI command that requires AWS credentials. See Using ShibboIeth for AWS APl and CLI accéss for directions. At the end of that, you will have a saml profile in your.awscredentials file. Note that thé point of pássing values to buiId arguments using énvironmnet variables is simpIy so that yóu can repeat thé build command muItiple times. It does nót obfuscate thém in the Dockér image history ór layer metadata. How Do I Specify Aws Shared Credentials File To The Docker Daemon Update Python RmStep 68: RUN wget s3.amazonaws.comaws-cliawscli-bundle.zip -O awscli-bundle.zip unzip awscli-bundle.zip apk add --update python rm varcacheapk.awscli-bundleinstall -i usrlocalaws -b usrlocalbinaws rm awscli-bundle.zip rm -rf awscli-bundle. Running cmd: usrbinpythón virtualenv.py --pythón usrbinpython usrlocalaws. ![]() That is whére the AWS CLl is invoked, ánd in this exampIe it shows thé output from thát as. The same appróach can be uséd with any othér Docker base imagé.
