问题描述
我正在尝试为perl脚本CooVar创建一个Docker容器，但是似乎由于tar命令不可用而遇到问题。
Dockerfile
FROM perl:5.20
RUN mkdir /tmp/install
workdir /tmp/install
# Install cpan modules
RUN cpanm install Cwd Getopt::Long POSIX File::Basename List::Util Bio::DB::Fasta Bio::Seq Bio::SeqUtils Bio::SeqIO Set::IntervalTree Set::IntSpan
# Download CooVar-v0.07
RUN wget -O /usr/local/bin/CooVar-0.07.tar.gz http://genome.sfu.ca/projects/coovar/CooVar-0.07.tar.gz
RUN tar xvf /usr/local/bin/CooVar-0.07.tar.gz
# Set workdir to /data -- predefined mount location.
RUN mkdir /data
workdir /data
# And clean up
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/install
# Set Entrypoint
ENTRYPOINT ["perl","/usr/local/bin/coovar-0.07/coovar.pl"]
注意：我认为这里使用
Entrypoint阻止了我通过Docker探索docker exec -t -i mycontainer /bin/bash容器文件系统，但这不是一个大问题我认为我从下面的错误中知道了问题所在。
错误
从Snakemake运行此程序时，我包括了ls /usr/bin so I can see what was in the container (very new to Docker and not sure the best way to develop/debug yet). You can see that the。tar.gz was not unzipped so it looks like tar在这种情况下不起作用。
