Docker 错误集合

no such file or directory

when build a Dockerfile ,and the file ‘redis.conf’ exists in real , but met such erro

Step 5 : RUN mkdir /usr/local/redis/
---> Running in 5cf73a52953f
---> 3351c41a56b4
Removing intermediate container 5cf73a52953f
Step 6 : COPY /home/dockerdir/Dockerfiles/redis.conf /usr/local/redis/conf/
**INFO[0007] home/dockerdir/Dockerfiles/redis.conf: no such file or directory** 

the reason:

• if you build using STDIN (docker build - < somefile) , this is no build context ,so COPY can’t be used
• COPY src dest ,here src just only filename without path ,so the file must exist in current build path ，and the dest must the folder with / or the certain filename

the reason

• the reason is the same like above ,the ADD or COPY destination must be a folder with / or the certain filename
