ubuntu ホスト マシンに docker rootless をインストールしました。最も重要な部分が次のようになっている timescaledb を構築するための Dockerfile があります。
# Install the tools we need for installation
RUN apt-get update && apt-get -y install gnupg2 lsb-release wget
# Add Postgres and Timescale package repository
RUN echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -c -s)-pgdg main" | tee /etc/apt/sources.list.d/pgdg.list
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
RUN sh -c "echo 'deb https://packagecloud.io/timescale/timescaledb/debian/ `lsb_release -c -s` main' > /etc/apt/sources.list.d/timescaledb.list"
RUN wget --quiet -O - https://packagecloud.io/timescale/timescaledb/gpgkey | apt-key add -
# Install Timescale
RUN apt-get update && apt-get -y install timescaledb-2-postgresql-12=2.0.0-zz~debian10
対応する docker-compose ファイルは次のようになります。
timescale:
tty: true
volumes:
- timescale-volume:/var/lib/postgresql/data:rw
build:
context: ./timescale
dockerfile: Dockerfile
command:
- /bin/bash
depends_on:
- cert-mounter
docker-compose upsudo で実行すると正常に動作し、イメージがビルドされ、コンテナーが実行されます。ルートレスで実行すると、次のエラーが発生します。

何が問題なのですか？他のコンテナはどうにか構築され、問題なくルートレスで実行されます...
