qdb-api-rest

I. Try it with docker

Preliminary

Download quasardb tools

Install qdb-server on your own machine to make qdb_user_add and qdb_cluster_keygen available.

wget https://download.quasardb.net/quasardb/nightly/server/qdb-3.0.0master-linux-64bit-server.tar.gz
tar qdb-3.0.0master-linux-64bit-server.tar.gz --no-same-owner -C /usr/local/
rm qdb-3.0.0master-linux-64bit-server.tar.gz

Generate a user key

/usr/local/bin/qdb_user_add -u tintin -s tintin.private -p users.cfg

Generate a cluster key

/usr/local/bin/qdb_cluster_keygen -p cluster.public -s cluster.private

Setup quasardb

docker pull bureau14/qdb:nightly

export QDB_QDDB_DIR=`pwd`/qdb-var-qdbd
mkdir $QDB_QDDB_DIR
cp users.cfg $QDB_QDDB_DIR/.
cp cluster.private $QDB_QDDB_DIR/.

Build

docker build -t qdb-api-rest-server .

Setup

export QDB_REST_DIR=`pwd`/qdb-var-rest
mkdir $QDB_REST_DIR
cp cluster.public $QDB_REST_DIR/.
cp rest-api.cfg $QDB_REST_DIR/.

Run

docker run -d -v $QDB_QDDB_DIR:/var/lib/qdb --name qdb-server bureau14/qdb:nightly --cluster-private-file /var/lib/qdb/cluster.private --user-list /var/lib/qdb/users.cfg

docker run -it --link qdb-server:qdb -v $QDB_REST_DIR:/var/lib/qdb -p 40080:40080 qdb-api-rest-server qdb://qdb:2836

II. Build locally

go get -u github.com/go-swagger/go-swagger/cmd/swagger
$GOPATH/bin/swagger generate server -f ./swagger.json -A qdb-api-rest -P models.Principal --exclude-main
cp configure_qdb_rest.go restapi/configure_qdb_rest.go
go install ./...
