moby: COPY fails intermittently no such file or directory

Description COPY command in Dockerfile fails intermittently with no such file or directory

Steps to reproduce the issue:

docker build -t dthompson55/mosquitto .
Dockerfile contains: COPY docker-entrypoint.sh /
Filesystem contains: -rwxrwxr-x 1 dant dant 30 Oct 3 11:50 docker-entrypoint.sh

Describe the results you received: —> 7be6a723492a Step 5 : COPY docker-entrypoint.sh / stat /var/lib/docker/aufs/mnt/5c714d1adb30f1366a6d12a49bc6529b88cb2887e71cf640a5daa5e989dac4ea/docker-entrypoint.sh: no such file or directory

Describe the results you expected:

I expected it to copy the file into the build context.

Additional information you deem important (e.g. issue happens only occasionally):

The build works a few times, and then fails. Once it fails I can’t get it to work again. If I reinstall everything on a clean ubuntu image then it works again, for a while.

docker - COPYing a file in a Dockerfile, no such file or directory? - Stack Overflow

I hit this as well, restarting the daemon fixed things…

(not that that is an ok fix, but it is a workaround 😃

This also occurs in combination with GitHub, Dockerhub and automated build. Also see this linke Docker Forums link

Also see: #27233

Keep in mind that source paths in COPY and ADD Dockerfile instructions are relative to the build context. So if you run

docker build -t foo .

The trailing . indicates the current directory; that directory is used as build-context, and sent to the docker daemon to use for the build.

What does your local directory look like? COPY /work/local.txt looks for a file named local.txt in the current directory, so if it’s missing, it fails:

$ mkdir repro-27134 && cd repro-27134

$ cat > Dockerfile -<<EOF
FROM httpd:2.4
COPY /work/local.txt /usr/local/apache2/htdocs/
EOF

$ docker build -t repro-27134 .

Step 2/2 : COPY /work/local.txt /usr/local/apache2/htdocs/
COPY failed: stat /var/lib/docker/tmp/docker-builder333585158/work/local.txt: no such file or directory

However, after creating the file;

$ mkdir work
$ echo "foobar" > work/local.txt

Building works;

$ docker build -t repro-27134 .
