factom-cli Docker Helper

The factom-cli Docker Helper is a simple tool to help build and run factom-cli as a container

Prerequisites

You must have at least Docker v17 installed on your system.

Having this repo cloned helps too 😇

Build

From wherever you have cloned this repo, run

docker build -t factom-cli_container .

(yes, you can replace factom-cli_container with whatever you want to call the container. e.g. factom-cli, foo, etc.)

Cross-Compile

To cross-compile for a different target, you can pass in a build-arg as so

docker build -t factom-cli_container --build-arg GOOS=darwin .

Run

docker run --rm factom-cli_container <some command here>

e.g.

docker run --rm factom-cli_container get heights

Note - In the above, replace factom-cli_container with whatever you called it when you built it - e.g. factom-cli, foo, etc.

Copy

So yeah, you want to get your binary out of the container. To do so, you basically mount your target into the container, and copy the binary over, like so

docker run --rm --entrypoint='' -v <FULLY_QUALIFIED_PATH_TO_TARGET_DIRECTORY>:/destination factom-cli_container /bin/cp /go/bin/factom-cli /destination

e.g.

docker run --rm --entrypoint='' -v /tmp:/destination factom-cli_container /bin/cp /go/bin/factom-cli /destination

which will copy the binary to /tmp/factom-cli

Note : You should replace ** factom-cli_container** with whatever you called it in the build section above e.g. factom-cli, foo, etc.

Cross-Compile

If you cross-compiled to a different target, your binary will be in /go/bin/<target>/factom-cli. e.g. If you built with --build-arg GOOS=darwin, then you can copy out the binary with

docker run --rm --entrypoint='' -v <FULLY_QUALIFIED_PATH_TO_TARGET_DIRECTORY>:/destination factom-cli_container /bin/cp /go/bin/darwin_amd64/factom-cli /destination

e.g.

docker run --rm --entrypoint='' -v /tmp:/destination factom-cli_container /bin/cp /go/bin/darwin_amd64/factom-cli /destination

which will copy the darwin_amd64 version of the binary to /tmp/factom-cli

Note : You should replace ** factom-cli_container** with whatever you called it in the build section above e.g. factom-cli, foo, etc.
