gitlab跨多个版本更新

1 背景

• 之前用的15.10.2版本，已经比较旧了：一方面是安全和兼容性风险越来越高，另一方面很多新功能、修复和维护工具都已经跟老版本脱节了

• gitlab更新比较麻烦，某些版本必须先停留，不能直接跨过去

2 下载安装包

按照官方升级路径查询，先准备好这些安装包。由于我用的是Ubuntu22.04系统，直接用deb包来装了。

#download.sh

#!/usr/bin/env bash
set -euo pipefail

BASE_URL="https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/jammy/pool/main/g/gitlab-ce"
ARCH="amd64"
OUTDIR="${1:-gitlab-ce-upgrade-packages}"

VERSIONS=(
  "15.11.13-ce.0"
  "16.3.9-ce.0"
  "16.7.10-ce.0"
  "16.11.10-ce.0"
  "17.3.7-ce.0"
  "17.5.5-ce.0"
  "17.8.7-ce.0"
  "17.11.7-ce.0"
  "18.2.8-ce.0"
  "18.5.5-ce.0"
  "18.8.9-ce.0"
  "18.11.0-ce.0"
)

mkdir -p "$OUTDIR"
cd "$OUTDIR"

for ver in "${VERSIONS[@]}"; do
  file="gitlab-ce_${ver}_${ARCH}.deb"
  url="${BASE_URL}/${file}"
  echo "Downloading ${file} ..."
  wget -c "$url"
done

echo
echo "Done. Packages saved in: $(pwd)"
ls -lh

3 漫长的升级过程

直接写了个脚本来一步步安装，安装前保证旧版本的gitlab正常运行，并且已经做好备份：

# install.sh

#!/usr/bin/env bash
set -euo pipefail

PACKAGES=(
  "gitlab-ce_15.11.13-ce.0_amd64.deb"
  "gitlab-ce_16.3.9-ce.0_amd64.deb"
  "gitlab-ce_16.7.10-ce.0_amd64.deb"
  "gitlab-ce_16.11.10-ce.0_amd64.deb"
  "gitlab-ce_17.3.7-ce.0_amd64.deb"
  "gitlab-ce_17.5.5-ce.0_amd64.deb"
  "gitlab-ce_17.8.7-ce.0_amd64.deb"
  "gitlab-ce_17.11.7-ce.0_amd64.deb"
  "gitlab-ce_18.2.8-ce.0_amd64.deb"
  "gitlab-ce_18.5.5-ce.0_amd64.deb"
  "gitlab-ce_18.8.9-ce.0_amd64.deb"
  "gitlab-ce_18.11.0-ce.0_amd64.deb"
)

for pkg in "${PACKAGES[@]}"; do
  echo "Installing $pkg ..."
  sudo dpkg -i "./$pkg"
  sudo gitlab-ctl reconfigure
  sudo gitlab-ctl restart
  echo "Check background migrations before continuing."
  sudo gitlab-rails runner 'puts Gitlab::BackgroundMigration.remaining'
  read -rp "Press Enter to continue to the next version..."
done

这个脚本好像执行到18.5.5左右版本时会报个小错误，可能是某个命令(gitlab-rails那行)太旧用法改变了，但不妨碍继续运行安装。
