docker-compose up: utf-8 codec can't decode byte X

Question

Everytime I run docker-compose up on my machine (macOS 10.13.5, latest docker version) I get this error

Traceback (most recent call last): File "docker-compose", line 6, in File "compose/cli/main.py", line 71, in main File "compose/cli/main.py", line 124, in perform_command File "compose/cli/command.py", line 41, in project_from_options File "compose/cli/command.py", line 126, in get_project File "compose/project.py", line 96, in from_config File "compose/network.py", line 320, in get_networks File "compose/network.py", line 125, in true_name File "compose/network.py", line 146, in _set_legacy_flag File "compose/network.py", line 106, in inspect File "site-packages/docker/utils/decorators.py", line 19, in wrapped File "site-packages/docker/api/network.py", line 211, in inspect_network

My first instinct is that this error means what it says: you somehow have the byte 0x80 in some file in your system (maybe not the docker-compose.yml) and it’s not UTF-8-encoded text. — David Maze

Ok so apparently there is a problem with the current version of docker-compose for macOS... It's just my guess, but anyhow here is how I solved it

curl -L https://github.com/docker/compose/releases/download/1.14.0-rc2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Then restarted the terminal

I ran into this same issue and this may also be related to your .env files.

Ensure that your .env files are UTF-8.

sudo apt install moreutils
isutf8 yourfile.env

If isutf8 returns no output it's likely a valid UTF-8 file.

Additionally, check the contents of the .env file you're referencing in your docker-compose.yml. Any incorrectly decrypted secrets/values you may be using locally can cause this problem too.

If in doubt, clear the env file and readd lines until you hit the error.

I have 2 ideas: 1. try to reinstall your python 2. use not the latest docker version, but the latest stable

i will try to re install python2, docker is already the latest stable version

tkrishtop Over a year ago

The issue is about python3.6 here: "/Users/distiller/compose-osx-release/compose/venv/lib/python3.6/codecs.py"

Ebram Sherif Over a year ago

I re installed python2 just to be sure. But in anycase I knew its not the issue, since I do not have python3 on my machine. Looks like docker has its own python enviroment .. distiller is not a user i have on my machine

@EbramSherif Check your git settings. Maybe you have windows line endings. stackoverflow.com/questions/10418975/…

What worked for me was creating an empty .env file in the directory I run docker-compose in (encoded as UTF-8).

If it's empty, it doesn't have an encoding.

Tobias Over a year ago

@tripleee Sounds reasonable, yes. Notepad++ shows UTF-8 as the encoding anyway. So I wanted to add this.

you need to go to the pycharm env file, double click it and install the python env file. Then run the code [docker-compose up airflow-init] again, it'll work.
