專案組現在需要接入CI/CD，其中就包括接入Harbor，本文將記錄如何在CentOS7.6機器上完成接入Harbor，
前期作業：首先需要在Harbor上開具賬號，創建相應專案（當前專案為imagetest），
設定Docker
默認開發機已完成Docker安裝：
# docker version
Client: Docker Engine - Community
Version: 20.10.16
API version: 1.41
Go version: go1.17.10
Git commit: aa7e414
Built: Thu May 12 09:19:45 2022
OS/Arch: linux/amd64
Context: default
Experimental: true
Server: Docker Engine - Community
Engine:
Version: 20.10.16
API version: 1.41 (minimum version 1.12)
Go version: go1.17.10
Git commit: f756502
Built: Thu May 12 09:18:08 2022
OS/Arch: linux/amd64
Experimental: false
containerd:
Version: 1.6.4
GitCommit: 212e8b6fa2f44b9c21b2798135fc6fb7c53efc16
runc:
Version: 1.1.1
GitCommit: v1.1.1-0-g52de29d
docker-init:
Version: 0.19.0
GitCommit: de40ad0
在/etc/docker/daemon.json檔案中（如果沒有daemon.json檔案，則自行創建此檔案）寫入如下資訊：
{
"insecure-registries": ["192.168.38.91:8090"]
}
檔案中的
192.168.38.91:8090為Harbor的部署地址，
設定完成后，需要重啟Docker，執行以下命令即可：
# systemctl daemon-reload
# systemctl restart docker
登錄Harbor
完成Docker設定后，需要手動執行登錄命令，以便確認Docker接入Harbor，
# docker login 192.168.38.91:8090
Authenticating with existing credentials...
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
推送鏡像
登陸完成后，即可在開發機上打包鏡像并推送至Harbor，
# 以下命令是Harbor推薦命令，我們可參照完成
# 192.168.38.91:8090/imagetest/是鏡像標記固定前綴，若未設定此前綴，鏡像將會被嘗試推送至docker.io
# 在專案中標記鏡像：
docker tag SOURCE_IMAGE[:TAG] 192.168.38.91:8090/imagetest/REPOSITORY[:TAG]
# 推送鏡像到當前專案：
docker push 192.168.38.91:8090/imagetest/REPOSITORY[:TAG]
在示例專案（Java專案）中創建Dockerfile，具體如下所示：
FROM openjdk:11.0.15-jdk
VOLUME /tmp
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone \
&& mkdir -p /opt/app/log
ARG JAR_FILE=*.jar
COPY ${JAR_FILE} /opt/app/app.jar
WORKDIR /opt/app/
ENTRYPOINT ["java","-Xms1g", "-Xmx1g","-verbose:gc", \
"-Xlog:gc,gc+ref=debug,gc+heap=debug,gc+age=trace:file=/opt/app/log/gc_%p.log:tags,uptime,time,level", \
"-Xlog:safepoint:file=/opt/app/log/safepoint_%p.log:tags,uptime,time,level", \
"-XX:+HeapDumpOnOutOfMemoryError", "-XX:HeapDumpPath=/opt/app/log/network-capability.hprof", \
"-XX:ErrorFile=/opt/app/log/hs_error_pid%p.log", "-XX:-OmitStackTraceInFastThrow", "-jar","/app.jar"]
執行以下命令完成鏡像打包和推送：
# 打包鏡像，并添加TAG：`192.168.38.91:8090/imagetest/demo:0.1`
docker build -t 192.168.38.91:8090/imagetest/demo:0.1 .
# 推送鏡像
docker push 192.168.38.91:8090/imagetest/demo:0.1
檢查Harbor倉庫，即可發現鏡像完成推送，
