tpm

Build and run the IBM TPM 2.0 simulator as well as the tpm2-tools.

Pull Docker Image

$ docker pull strongx509/tpm

Build Docker Image

Alternatively the docker image can be built from scratch in the tpm directory with

$ docker build -t strongx509/tpm .

The build rules are defined in Dockerfile.

Create Docker Container

$ docker-compose up
Creating tpm-server ... done
Attaching to tpm-server

with the setup defined in docker-compose.yml.

In an additional console window we open a bash shell to start the IBM TPM 2.0 simulator in the tpm-server container

$ docker exec -ti tpm-server /bin/bash
# /usr/bin/tpm_server &
