背景介绍
在我参与的一个国企项目中，我们基于大语言模型开发了一些应用，但是甲方公司所有的资源环境都是纯内网。更为有趣的是，甲方公司已自主搭建并运行着一套百度机器学习平台（BML），客户要求所有的大模型部署必须依托于现有的BML平台进行，而非独立构建全新的基础设施，资源申请也相当严苛。面对这一系列限定条件，我们只能试着利用Docker容器技术进行大语言模型的部署。
前期准备
1、首先，内网环境部署docker：
这部分内容不再赘述，可参考之前写的教程。
bash
https://zyn1994.blog.csdn.net/article/details/1095161912、其次，使用一台具备网络环境的设备，拉取ollama的基础镜像：
bash
docker pull ollama/ollama:latest
# 如果拉取不到，可使用下面这个
docker pull dhub.kubesre.xyz/ollama/ollama:latest3、下载Qwen2的GGUF模型，这里为了演示方便就下载0.5B的模型了。
下载地址：https://huggingface.co/Qwen/Qwen2-0.5B-Instruct-GGUF或者https://modelscope.cn/models/qwen/Qwen2-0.5B-Instruct-GGUF
4、编写Modelfile文件：
bash
# 注意GGUF模型文件的地址要与Dockerfile中保持一致
FROM /tmp/qwen2-0_5b-instruct-q4_0.gguf
TEMPLATE "{{ if .System }}<|im_start|>system
{{ .System }}<|im_end|>
{{ end }}{{ if .Prompt }}<|im_start|>user
{{ .Prompt }}<|im_end|>
{{ end }}<|im_start|>assistant
{{ .Response }}<|im_end|>
"
PARAMETER stop <|im_start|>
PARAMETER stop <|im_end|>最终得到GGUF模型文件和Modelfile文件。
bash
-rw-r--r--. 1 root root 290 Jun 21 14:00 Modelfile
-rw-r--r--. 1 root root 352969408 Jun 21 13:44 qwen2-0_5b-instruct-q4_0.gguf构建镜像
1、将先前拉取的基础镜像导入内网设备，然后编写Dockerfile文件：
bash
FROM ollama:latest
EXPOSE 11434
ADD Modelfile /tmp/Modelfile
ADD qwen2-0_5b-instruct-q4_0.gguf /tmp/qwen2-0_5b-instruct-q4_0.gguf
ENTRYPOINT ["sh","-c","/bin/ollama serve"]2、构建docker镜像，执行docker build -t ollama_qwen2-0_5b:1.0 -f Dockerfile .：
bash
(base) [root@localhost docker-qwen2]# docker build -t ollama_qwen2-0_5b:1.0 -f Dockerfile .

=> => naming to docker.io/library/ollama_qwen2-0_5b:1.0 运行容器
1、创建并运行容器，执行docker run -itd --name ollama_qwen2 -p 11434:11434 ollama_qwen2-0_5b:1.0
bash
(base) [root@localhost docker-qwen2]# docker run -itd --name ollama_qwen2 -p 11434:11434 ollama_qwen2-0_5b:1.0
b034390bf79ceca1ec67bb4f9898c930c2a6efe8260bb8ba0fcbe5ffd2634f1a2、验证docker容器是否执行成功：
bash
(base) [root@localhost docker-qwen2]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0341f573e41f ollama_qwen2-0_5b:1.0 "sh -c '/bin/ollama ..." 6 seconds ago Up 3 seconds 0.0.0.0:11434->11434/tcp, :::11434->11434/tcp ollama_qwen2到这里，我们已经部署好了docker版的ollama。这时ollama里并没有运行任何的模型，还需要我们进入容器创建加载一下。
加载Qwen2模型
1、首先进入我们刚刚运行的容器：
bash
docker exec -it 0341f573e41f /bin/bash2、执行ollama create命令，创建及加载Qwen2模型：
bash
root@0341f573e41f:/# ollama create qwen:0.5b -f /tmp/Modelfile
transferring model data
using existing layer sha256:aca679832ded61145239ce7f5c5ebddb1c57ada786c9c23733899c3888e0596f

creating new layer sha256:a82ce90cbc26a4c59e0985d2bceffa1d2616a1579218ff3cb656a3252cafdcc0
writing manifest
success3、以上内容显示Qwen2模型已经成功在ollama中运行，然后输入exit退出容器即可。
问答测试
1、基于我自己写的open-ai-java的框架，访问Ollama服务的代码：
bash
# 访问代码
public static void test0(){
OpenAIChat openAIChat = OpenAIChat.builder()
.endpointUrl("http://10.8.xxx.xxx:11434/v1")
.model("qwen:0.5b")
.build().init();
String stringFlux = openAIChat.chat("0dbe1580-60ae-4440-9462-df0a8f629f2c","你好");
System.out.println(stringFlux);
}
# Idea中的响应日志
17:05:32.370 [main] INFO com.xxx.openai.llms.OpenAIChat - OpenAI 请求参数: {top_p=0.78, max_tokens=20000, temperature=0.9, messages=[Message(role=user, content=你好)], model=qwen:0.5b}
17:05:34.547 [main] INFO com.xxx.openai.llms.OpenAIChat - OpenAI 处理成功 响应结果为:

{"id":"chatcmpl-675","object":"chat.completion","created":1718960749,"model":"qwen:0.5b","system_fingerprint":"fp_ollama","choices":[{"index":0,"message":{"role":"assistant","content":"您好！有什么我可以帮助您的吗？"},"finish_reason":"stop"}],"usage":{"prompt_tokens":9,"completion_tokens":9,"total_tokens":18}}2、查询docker容器中的日志，可以看到服务运行良好：
bash
(base) [root@localhost docker-qwen2]# docker logs -f 0341f573e41f
