Building Tools

We currently build the tools with Go version 1.15. Other Go versions may work but they are untested.

Using go get to directly build the tools will not work. To build them, it's recommended to first clone this repository:

git clone
cd mongo-tools

Then run ./make build to build all the tools, placing them in the bin directory inside the repository.

You can also build a subset of the tools using the -tools option. For example, ./make build -tools=mongodump,mongorestore builds only mongodump and mongorestore.

To use the build/test scripts in this repository, you must set GOROOT to your Go root directory. This may depend on how you installed Go.

export GOROOT=/usr/local/go

Updating Dependencies

Starting with version 100.3.1, the tools use go mod to manage dependencies. All dependencies are listed in the go.mod file and are directly vendored in the vendor directory.

In order to make changes to dependencies, you first need to change the go.mod file. You can manually edit that file to add/update/remove entries, or you can run the following in the repository directory:

go mod edit -require=<package>@<version>  # for adding or updating a dependency
go mod edit -droprequire=<package>        # for removing a dependency

Then run go mod vendor -v to reconstruct the vendor directory to match the changed go.mod file.

Optionally, run go mod tidy -v to ensure that the go.mod file matches the mongo-tools source code.
