Docker Dockerfile
Dockerfile 是一个用来构建镜像的文本文件，文本内容包含了一条条构建镜像所需的指令和说明。
本文在制作 BERT 文本分类模型镜像时，碰到的 docke build 的 pip 错误：
OCI runtime create failed: container_linux.go:345: starting container process caused “exec: “pip”: executable file not found in $PATH”: unknown
Dockefile 制作镜像
使用 pip 安装依赖包：
pip install -r /home/bert_model/requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
写成 Dockefile 的命令：
RUN ["pip", "install", "-r", "/home/bert_model/requirements.txt", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"]
Dockefile：
FROM refazul/python3.9.0
ADD bert_model.tar /home
RUN ["pip", "install", "-r", "/home/bert_model/requirements.txt", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"]
ENTRYPOINT ["bash", "/home/bert_model/run.sh"]
创建镜像
docker build -t bert_model:v1 .
报错信息
详细报错信息如下：
OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"pip\": executable file not found in $PATH": unknown
解决方法
先创建测试容器
docker run -it -d \
--name test_v2 \
-v /bee/test_model/:/notebooks \
-e TZ='Asia/Shanghai' \
--shm-size 16G \
refazul/python3.9.0:latest
再进入容器
docker exec -it test_v2 bash
查找 pip 路径
执行：
whereis pip
输出：
# whereis pip
pip: /root/.pyenv/shims/pip3.9 /root/.pyenv/shims/pip
可以看出 pip 不在默认的 $PATH 路径下面
修改 pip 路径
修改 Dockefile 中的 pip 命令
RUN ["pip", "install", "-r", "/home/bert_model/requirements.txt", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"]
为：
RUN ["/root/.pyenv/shims/pip", "install", "-r", "/home/bert_model/requirements.txt", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"]
Dockefile：
FROM refazul/python3.9.0
ADD bert_model.tar /home
RUN ["/root/.pyenv/shims/pip", "install", "-r", "/home/bert_model/requirements.txt", "-i", "https://pypi.tuna.tsinghua.edu.cn/simple"]
ENTRYPOINT ["bash", "/home/bert_model/run.sh"]
再执行：
docker build -t bert_model:v1 .
执行成功，输出：
