[#sonatype-nexus3-docker-arm64-install-requirement]
|
|
=== 安装前准备
|
|
由于 nexus 没有官方提供支持 arm 架构的 docker 镜像，我们需要自行构建镜像，在构建之前，需要准备好构建镜像相关的文件:
|
|
|
|
. 需要从官网下载 nexus-${version}-unix.tar.gz 文件
|
|
. link:resources/files/9999-appendix/docker/nexus/Dockerfile[Dockerfile]
|
|
|
|
TIP:: 直接访问 https://www.sonatype.com/thanks/repo-oss 可直接进入下载页面
|
|
|
|
以下是 Dockerfile 文件内容及说明:
|
|
[source,bash]
|

=== 构建支持 linux/arm64 镜像
|
|
以下将以 nexus-3.51.0-01 版本为例:
|
|
|
|
[source,bash]
|
|
----
|
|
# 1. 创建用户构建 docker 镜像工作目录
|
|
mkdir /Users/wangshaoping/wspsc/software/docker/Dockerfile/nexus3-docker-arm64
|
|
|
|
# 2. 将事先准备好的 nexus-3.51.0-01-unix.tar.gz 文件复制到上面新建的镜像工作目录中
|
|
# 3. 在镜像工作目录中新建名为 Dockerfile 文件, 文件内容可从上一节中直接下载
|
|
|
|
# 4. 构建镜像
|
|
docker buildx build --pull \
|
|
--platform "linux/arm64" \
|
|
--tag "sonatype/nexus3-arm64:3.51.0-01" \
|
|
--output=type=docker \
|
|
.
|
|
----
|
|
|
|
=== save 新构建的镜像
|
|
[source,bash]
|
|
----
|
|
# 保存新构建的镜像成 tar 文件以便后续直接 load 使用
|
|
docker save -o nexus3-3.51.0-01-arm64.tar sonatype/nexus3-arm64:3.51.0-01
|
|
|
|
# load 镜像 tar 文件
|
|
docker load --input nexus3-3.51.0-01-arm64.tar
|
|
----
|
|
|
|
=== 启动容器
|
|
[source,bash]
|
|
----
|
|
docker run \
|
|
--name nexus \
|
|
-d \
|
|
-p 8000:8081 \
|
|
-v /Users/wangshaoping/wspsc/software/docker/volume/nexus_v3:/nexus-data \
|
|
sonatype/nexus3-arm64:3.51.0-01
|
|
|
|
# 需要等待一定的时间,可通过以下命令查看日志
|
|
docker logs -f nexus
|
|
|
|
# 当控制台出现类似以下内容时,表示容器已经启动好了。
