概要

状況を整理するためにメモ
(バグなのか、環境変数等が足りないせいなのかまだ判別がついていない状態です)

ちゃんと、バージョンアップする前にbackupを取らないとだめですね。。。

環境

ホストOS: Ubuntu 14.04
Docker: Docker version 1.12.3, build 6b644ec
docker compose:docker-compose version 1.8.1, build 878cff1
Dockerコンテナ:
- sameersbn/gitlab:8.16.6 //8.12.3からアップグレード
- sameersbn/redis:latest
- sameersbn/postgresql:9.5-1
直接は関係ないが以下のコンテナもいっしょに起動している
- fluentd/fluend
- kibana:4.6.2
- elasticsearch:2.4.1

症状

バックアップのRakeタスクを実行するとエラーが発生する


$ docker-compose run --rm gitlab app:rake gitlab:backup:create

1回目

$ docker-compose run --rm gitlab app:rake gitlab:backup:create

(メモ撮り忘れた)

fatal: Need a repository to create a bundle.

2回目(dbがバックアップできなくなりました)

$ docker-compose run --rm gitlab app:rake gitlab:backup:create

Githubみるとバックアップ関連のissueがいくつか上がっている

遭遇したエラーとは別なので直接関係はないかもだが。

I have created an issue for the other problem (#1122). It seems that there are a lot of backup related problems in 8.16.6.

とあるのでほかにもいくつか不具合があるのかも。

アップデートは可能だが、ダウングレードは単純にコンテナ差し替えるだけだとできないので注意

試しに、gitlab:8.15.4にダウングレードしようとすると、下記のエラーがでて起動しませんでした。
(おそらくバージョンアップ前のバックアップからrestoreしないとだめ)
