Docker环境编译时的两个错误记录

Posted 2020-11-04 kevingrace

 

1）报错一
docker-compose -f compose/app.yaml -f compose/backend.yaml -f compose/proxy.yaml build peatio barong
ERROR: Couldn‘t connect to Docker daemon at http://localhost:4243 - is it running?

If it‘s at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
make: *** [build] Error 1

解决办法：

1）查看配置文件
[[email protected] ~]# systemctl show docker | grep FragmentPath=
FragmentPath=/usr/lib/systemd/system/docker.service

然后修改/lib/systemd/system/docker.service文件
[[email protected] ~]# cp /lib/systemd/system/docker.service /lib/systemd/system/docker.service.bak
[[email protected] ~]# vim /lib/systemd/system/docker.service
.......
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:4243                  #添加这一行
#ExecStart=/usr/bin/dockerd-current \                                                            #注释掉默认的这一行
          --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \        
          --default-runtime=docker-runc           --exec-opt native.cgroupdriver=systemd           --userland-proxy-path=/usr/libexec/docker/docker-proxy-current           --seccomp-profile=/etc/docker/seccomp.json           $OPTIONS           $DOCKER_STORAGE_OPTIONS           $DOCKER_NETWORK_OPTIONS           $ADD_REGISTRY           $BLOCK_REGISTRY           $INSECURE_REGISTRY     $REGISTRIES

2）修改/etc/default/docker文件
[[email protected] ~]# cp /etc/default/docker /etc/default/docker.bak
[[email protected] ~]# vim /etc/sysconfig/docker
......
DOCKER_OPTS="-H tcp://localhost:4243 -H unix:///var/run/docker.sock"          #添加这一行

3）DOCKER_HOST的环境变量设置
[[email protected] ~]# vim ~/.bashrc 
........
export DOCKER_HOST=tcp://localhost:4243

4）重启docker服务
[[email protected] ~]# systemctl daemon-reload
[[email protected] ~]# systemctl restart docker

5）检查发现4243端口已启动
[[email protected] ~]# netstat -ant
.......
tcp6       0      0 :::4243                 :::*                    LISTEN     
[[email protected] ~]# lsof -i:4243
COMMAND     PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
dockerd-c 15400 root    6u  IPv6  59175      0t0  TCP *:4243 (LISTEN)

2）报错二
ERROR: Service ‘****‘ failed to build: shim error: docker-runc not installed on system
