DAOS-在docker中搭建daos开发调试环境

简介

本节介绍如何在 Docker 容器中构建和运行 DAOS 服务。 至少需要 4GB DRAM 和 16GB 磁盘空间。 在 Mac 上，请确保“Preferences/{Disk, Memory}”下的 Docker 设置已进行相应配置

步骤

拉取项目

1

git clone https://github.com/ssbandjl/daos.git

下载依赖包(缓存cache)

1

cd daos; wget http://rz2fg6ogr.hn-bkt.clouddn.com/cache_tgz

编译镜像或下载我这边已经编好的镜像

1
2

编译镜像: docker build  . -f utils/docker/Dockerfile.el.8 -t daos
# 已编好的镜像: wget http://rz2fg6ogr.hn-bkt.clouddn.com/daos_main.tgz; docker load -i daos_main.tgz

查看docker镜像:
[root@node3 daos]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
daos         latest    8a64df225def   2 weeks ago   3.16GB

给宿主机配置大页(如8GB):
永久生效
tee<<EOF>>/etc/sysctl.conf
vm.nr_hugepages = 4096
EOF
sysctl -p

启动docker镜像:
docker run -it -d --privileged --cap-add=ALL --name daos_main1 -v /home/xb/project/stor/daos/main/daos:/home/xb/project/stor/daos/main/daos -v /dev:/dev -v /dev/hugepages:/dev/hugepages -v /sys/fs/cgroup:/sys/fs/cgroup:ro daos:latest

进入镜像: docker exec -u root -it daos_main1 bash -c 'cd /home/xb/project/stor/daos/main/daos;exec "${SHELL:-sh}"'

重新编译并安装DAOS:
./build.sh 或
scons --jobs 1 install PREFIX=/opt/daos BUILD_TYPE=debug TARGET_TYPE=debug --build-deps=yes

which dmg

拷贝证书和配置(启动时根据提示修改权限):
cp -r daosCA/certs /etc/daos/

参考配置文件: daos_server_docker_main.yml

# source /root/.bashrc
# run_all "pkill daos_agent;pkill daos_server"

source /root/.bashrc
pkill daos_agent 
pkill daos_server
rm -f /tmp/daos*.log

#     joined_num=`dmg sys query -v|grep Joined|wc -l`
#     if [[ $joined_num -eq 3 ]];then
#         break
#     fi
#     echo -e "wait all rank join, $count times"
#     count=$((count+1))
#     sleep 1
# done

sleep 5
dmg storage format


创建池,容器, 挂载daos文件系统:
参考文件: daos_create_pool_cont_mount_dfuse
dmg pool create sxb -z 4g; dmg pool list --verbose
daos container create sxb --type POSIX sxb; daos container query sxb sxb --verbose; daos cont get-prop sxb sxb
mkdir -p /tmp/sxb; dfuse --mountpoint=/tmp/sxb --pool=sxb --cont=sxb; df -h
#cd /tmp/sxb

最终效果:
