1. While building the image in Jenkins, an error occurred: Error processing tar file(exit status 1): unexpected EOF. See Figure 1.

2. After reviewing the Dockerfile, it appears that having too many ADD commands caused insufficient space. Reference URL: https://stackoverflow.com/questions/42784396/docker-error-error-processing-tar-fileexit-status-1-unexpected-eof . See Figure 2.

3. Move /build/sync.sh to /build/c_files/usr/share/sync.sh. Move /build/cacheJsSDK.sh to /build/c_files/usr/share/cacheJsSDK.sh. Move /build/MP_verify_3RUFnkMVef9eh3mJ.txt to /build/c_files/mcloud/cmp_main/MP_verify_3RUFnkMVef9eh3mJ.txt. Move /build/MP_verify_qxIMkC3go7fNqBzb.txt to /build/c_files/mcloud/cmp_main/MP_verify_qxIMkC3go7fNqBzb.txt. Edit the Dockerfile and remove 4 ADD lines. See Figure 3.

4. Build again. The first build failed with the error: unknown parent image ID sha256:. However, the second build succeeded. See Figure 4.

5. The image sizes before and after the adjustment were 4711 and 3882, respectively. The size decreased by 4711 – 3882 = 829. See Figure 5.

6. Another possible cause is that the Dockerfile has just undergone major modifications. In this case, I recommend building a few more times. It will eventually build successfully.
