pip3 install ibm_db 在 docker 映像中失败

Question

I'm trying to have a python serive running on a Linux Ubuntu machine. My Dockerfile has a command that successfully installs all dependecies in requirement.txt, but fails for ibm_db due to time out error. Dockerfile sample below:

FROM python:3.5

# This fails
RUN pip3 install ibm_db

# This passes without ibm_db
RUN pip3 install -r /root/bags/requirements.txt

Error printed on console:

Step 2/3 : RUN pip3 install ibm_db

Answer 1

I could not recreate the issue. The build with the provided Dockerfile and requirements.txt completes successfully. That rules out an issue of your dockerfile and points to an infrastructure issue.

Second, your step pip3 install ibm_db fails. Taking a closer look at that we can see it fails to download:

https://public.dhe.ibm.com/ibmdl/export/pub/software/data/db2/drivers/odbc_cli/linuxx64_odbc_cli.tar.gz

can you try to curl this from your host / within the container? Are both curls successful? Do you now have the linuxx64_odbc_cli.tar.gz after executing the curl in your current folder?

curl https://public.dhe.ibm.com/ibmdl/export/pub/software/data/db2/drivers/odbc_cli/linuxx64_odbc_cli.tar.gz > linuxx64_odbc_cli.tar.gz

My hypothesis is that you are behind a firewall/proxy that does not allow you to download this particular file. If you can download it without any issues, we could rule out firewall/proxy as the culprit.

Answer 2

I suggest you to run update first:

FROM python:3.5

RUN apt-get update
RUN pip install --upgrade pip
