Work in progress.
This is an Go interface for DAOS which is also a work in progress. Building this requires a local DAOS build and DAOS server running, so start there first.
Only basic Pool commands have been implemented so far.
This is a Go project, so a Go development tools are naturally required. We recommend the most current Go release availble, curently 1.7.4.
Setup environment and build. This assumes $daospath is set as it was in the DAOS README
export GOPATH=$HOME/go
export LD_LIBRARY_PATH=${daospath}/install/lib
export PATH=${daospath}/install/bin:$PATH
export CGO_CPPFLAGS="-I${daospath}/install/include -I${daospath}/src/include"
export CGO_LDFLAGS=-L${daospath}/install/lib
go get -u github.com/rread/go-daos/cmd/dcmd
The last command will clone this repo and and its dependencies, build,
and install in the Go workspace. The dcmd binary will be in
$GOPATH/bin/dcmd and the source for the package will be
$GOPATH/src/github.com/rread/go-daos. You can build again using:
go install github.com/rread/go-daos/cmd/dcmd
Also includes a simple CLI tool for interacting with DAOS. This tool requires the orterun command that was built for DAOS to be on the command line, and will handle running itself with orterun if is run directly. When dcmd calls orterun itself, the default uri file is /tmp/daos-uri or it can be customized with --uri option. See command help for more options and command details.
This will create a single object and attempt to write and then read a value:
cont=$(uuidgen)
export DAOS_GROUP="" # if needed
export DAOS_POOL=$(dcmd pool create)
dcmd cont create --uuid $cont
dcmd object hello --cont $cont --value "world"
