How to install terraform 0.12 in an alpine container with apk?

Question

I want to add terraform version 0.12.21 in an alpine container, but I can only add 0.11.0 using apk. If I try to add it as the desired version I get the following error:

/ # apk upgrade terraform==0.12.21-r0
OK: 192 MiB in 66 packages
/ # apk add terraform==0.12.21-r0
ERROR: unsatisfiable constraints:
  terraform-0.11.0-r0:
    breaks: world[terraform=0.12.21-r0]

How do I fix this apk error?

Use the Terraform Docker image instead. – Sherrillsherrington

Answer 1

I havent found an apk solution but I can just download the desired binary and replace the existing one with the following in the dockerfile:

# upgrade terraform to 0.12.21
RUN wget https://releases.hashicorp.com/terraform/0.12.21/terraform_0.12.21_linux_amd64.zip
RUN unzip terraform_0.12.21_linux_amd64.zip && rm terraform_0.12.21_linux_amd64.zip
RUN mv terraform /usr/bin/terraform

After doing these commands, running terraform does not work because it cannot be found. – Endpaper

I'm documenting @SantaXL's comment as an answer just to make it easier to find in the future.

apk add terraform --repository=https://dl-cdn.alpinelinux.org/alpine/edge/community

This doesn't specifically add version 0.12, as per the question. Instead, it installs the latest version of terraform held in the Alpine repository. Note that this isn't necessarily the latest version of terraform, but it usually is.

This is the better solution, because it automatically picks the latest stable version. – Tumbling

Just to be clear, doing this means that you are installing the latest terraform version from the Alpine repository. So you cannot really choose which terraform version you want, you are bound to be using the one that is in the repository. – Endpaper

Thanks @Endpaper -- You're right about the clarification so I've added it to the answer to make it more explicit. – Bors

If need special the version, try this command apk add terraform=1.2.5-r0 --repository=https://dl-cdn.alpinelinux.org/alpine/edge/community – Upi

For example:

apk add terraform --repository=http://dl-cdn.alpinelinux.org/alpine/v3.12/main

where 3.12 is apk's branch

The latest would be: apk add terraform --repository=http://dl-cdn.alpinelinux.org/alpine/edge/main But still, it gives outdated v0.12.25 – Argyll

@VladimirVukanac that's incorrect. Open in your browser http://dl-cdn.alpinelinux.org/alpine/edge/main - outdated 0.12.25. But if you open http://dl-cdn.alpinelinux.org/alpine/edge/community, you've got the latest version. In other words, use apk add terraform --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community. Check repository column on this site: https://pkgs.alpinelinux.org/packages?name=terraform&branch=edge&arch=x86_64 – Allhallows

Maybe I did something wrong during the process, but purely by running this in Dockerfile I got that version. Here is an example: docker run --rm -it $(echo "FROM alpine\nRUN apk add terraform --repository=http://dl-cdn.alpinelinux.org/alpine/edge/main" | docker build -q - ) sh -c "terraform --version" The result is: Terraform v0.12.25 Your version of Terraform is out of date! The latest version is 0.13.5. You can update by downloading from https://www.terraform.io/downloads.html – Argyll

Nice! Thanks! This: docker run --rm -it $(echo "FROM alpine\nRUN apk add terraform --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community" | docker build -q - ) sh -c "terraform --version" gives the latest version: Terraform v0.13.5 – Argyll
