执行 docker-compose 时出错：构建网络服务器无法准备上下文：无法“git clone”到临时上下文目录：获取错误

Question

I'm following this Apache Airflow tutorial and I'm failing to execute

docker-compose up -d

command. I get following error:

Building webserver
unable to prepare context: unable to 'git clone' to temporary context directory: error fetching: /usr/lib/git-core/git-remote-https: /tmp/_MEItH0v3Q/libcrypto.so.1.1: version `OPENSSL_1_1_1' not found (required by /lib/x86_64-linux-gnu/libssh.so.4)
: exit status 128
ERROR: Service 'webserver' failed to build

I'm using Ubuntu 20.04 on WSL2 .

I've installed exactly that version of OPEN SSL - OPENSSL_1_1_1 but error remains. I've also updated git to 2.30.2 because I've read it could fix it but no luck.

I've just encountered the same problem. I'm only starting with docker and airflow, so I can't really say why this fix works, but it works, so here it is:

Change in docker-compose.yaml a tag for puckel/docker-airflow from 1.10.1 to 1.10.9 .
Your webserver section in docker-compose.yaml file should start like this:

webserver:
    image: puckel/docker-airflow:1.10.9
    build:
      context: https://github.com/puckel/docker-airflow.git#1.10.9
      dockerfile: Dockerfile

Answer 2

Also getting this after downloading a fresh docker-compose version. I'm also on Ubuntu 20.04.2 LTS, docker-compose version 1.29.1, build c34c88b2 .

Downgrading to 1.27.4 "resolve" the error…

Isn't it supposed to be statically linked?

Answer 3

I had the same issue. Apparently this is a known bug for docker-compose 1.29 and Ubuntu 20 [1]

My docker-compose was installed using curl .

What worked for me was removing docker-compose and install it using pip instead:

sudo rm /usr/local/bin/docker-compose
pip3 install docker-compose 

After that everything worked as expected.
