Images built off of this PR, that you can try, base:

ghcr.io/surajssd/cloudshell/base:add-tools-to-base-3496268-20241029-000708

and tools:

ghcr.io/surajssd/cloudshell/tools:add-tools-to-base-3496268-20241029-000708

---

Above images have following az cli version:

$ docker run -it ghcr.io/surajssd/cloudshell/base:add-tools-to-base-3496268-20241029-000708 az version --output json | jq -r '."azure-cli"'
2.65.0

$ docker run -it ghcr.io/surajssd/cloudshell/tools:add-tools-to-base-3496268-20241029-000708 az version --output json | jq -r '."azure-cli"'
2.65.0

Since az cli now has a new release, I built a new tools image based off of the above base image which is shipping 2.65.0 and the new tools image can override the base with new az cli version, build the new tools image:

docker build \
   -t tools_cloudshell \
   --build-arg IMAGE_LOCATION=ghcr.io/surajssd/cloudshell/base:add-tools-to-base-3496268-20241029-000708 \
   -f linux/tools.Dockerfile .

$ docker run -it tools_cloudshell az version --output json | jq -r '."azure-cli"'
2.66.0

Azure CLI is being overridden, but the powershell fails:

$ docker run \
   --volume $(pwd)/tests:/tests \
   -it tools_cloudshell \
   /tests/test.sh

With the latest changes the tests also pass. To test this PR, build the latest tools off of the base:

docker build \
   -t tools_cloudshell \
   --build-arg IMAGE_LOCATION=ghcr.io/surajssd/cloudshell/base:add-tools-to-base-3496268-20241029-000708 \
   -f linux/tools.Dockerfile .

Run regular tests:

docker run \
   --volume $(pwd)/tests:/tests \
   -it tools_cloudshell \
   /tests/test.sh

Check the new az cli version like mentioned in: #506 (comment) and check az cli in base image to see the difference and how it is being overridden.
