Error processing tar file(exit status 1): unexpected EOF 的排查分析

Post Views: 302

1、在 Jenkins 中构建镜像，报错：Error processing tar file(exit status 1): unexpected EOF。如图1



Step 10/10 : RUN chown -R nginx:nginx /mcloud/ &&     chmod 777 /mcloud/cmp_main/data &&     chmod 777 /usr/share/sync.sh &&     chmod 777 /mcloud/cmp_main/attachment &&     chmod +x /config/init/* &&     chmod +x /etc/nginx/conf.d/* &&     chmod +x /etc/supervisord.d/* &&     rm -rf /mcloud/cmp_main/data/tpl/ &&     rm -rf /etc/nginx/conf.d/status.conf

Error processing tar file(exit status 1): unexpected EOF
Build step 'Docker Build and Publish' marked build as failure
Finished: FAILURE

2、查看 Dockerfile ，应该是 ADD 命令的行数过多了一些，进而导致空间不足。参考网址：https://stackoverflow.com/questions/42784396/docker-error-error-processing-tar-fileexit-status-1-unexpected-eof 。如图2



ADD code /mcloud/cmp_main
ADD code/build/c_files/ /
ADD code/build/sync.sh /usr/share/sync.sh
ADD code/build/cacheJsSDK.sh /usr/share/cacheJsSDK.sh
ADD code/build/MP_verify_3RUFnkMVef9eh3mJ.txt /mcloud/cmp_main/
ADD code/build/MP_verify_qxIMkC3go7fNqBzb.txt /mcloud/cmp_main/

RUN sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
    sed -i 's/disable_functions = exec,system/disable_functions = system/g' /usr/local/php/etc/php.ini

RUN chown -R nginx:nginx /mcloud/ && \
    chmod 777 /mcloud/cmp_main/data && \
    chmod 777 /usr/share/sync.sh && \
    chmod 777 /mcloud/cmp_main/attachment && \
    chmod +x /config/init/* && \
    chmod +x /etc/nginx/conf.d/* && \
    chmod +x /etc/supervisord.d/* && \
    rm -rf /mcloud/cmp_main/data/tpl/ && \
    rm -rf /etc/nginx/conf.d/status.conf

3、剪切 /build/sync.sh 至 /build/c_files/usr/share/sync.sh。剪切 /build/cacheJsSDK.sh 至 /build/c_files/usr/share/cacheJsSDK.sh。剪切 /build/MP_verify_3RUFnkMVef9eh3mJ.txt 至 /build/c_files/mcloud/cmp_main/MP_verify_3RUFnkMVef9eh3mJ.txt。剪切 /build/MP_verify_qxIMkC3go7fNqBzb.txt 至 /build/c_files/mcloud/cmp_main/MP_verify_qxIMkC3go7fNqBzb.txt。编辑 Dockerfile，删除了 4 行 ADD。如图3

剪切 /build/sync.sh 至 /build/c_files/usr/share/sync.sh。剪切 /build/cacheJsSDK.sh 至 /build/c_files/usr/share/cacheJsSDK.sh。剪切 /build/MP_verify_3RUFnkMVef9eh3mJ.txt 至 /build/c_files/mcloud/cmp_main/MP_verify_3RUFnkMVef9eh3mJ.txt。剪切 /build/MP_verify_qxIMkC3go7fNqBzb.txt 至 /build/c_files/mcloud/cmp_main/MP_verify_qxIMkC3go7fNqBzb.txt。编辑 Dockerfile，删除了 4 行 ADD。 — 图3



RUN sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
    sed -i 's/disable_functions = exec,system/disable_functions = system/g' /usr/local/php/etc/php.ini

ADD code /mcloud/cmp_main
ADD code/build/c_files/ /

RUN chown -R nginx:nginx /mcloud/ && \
    chmod 777 /mcloud/cmp_main/data && \
    chmod 777 /usr/share/sync.sh && \
    chmod 777 /mcloud/cmp_main/attachment && \
    chmod +x /config/init/* && \
    chmod +x /etc/nginx/conf.d/* && \
    chmod +x /etc/supervisord.d/* && \
    rm -rf /mcloud/cmp_main/data/tpl/ && \
    rm -rf /etc/nginx/conf.d/status.conf

4、再次构建，第一次构建报错：unknown parent image ID sha256:。不过第二次构建成功。如图4

5、调整前后的镜像大小分别为：4711、3882。大小减少了：4711 – 3882 = 829。如图5

6、另一个可能的原因在于 Dockerfile 刚经过大幅度的修改。此种情况下，建议多构建几次。最终还是可以构建成功。
