Python/Docker ImportError: cannot import name 'json' from itsdangerous

Asked 2022-Mar-31 at 12:49

I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.

I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.

QUESTION

Why should I run multiple elasticsearch nodes on a single docker host?

Asked 2022-Mar-09 at 18:17

There are a lot of articles online about running an Elasticsearch multi-node cluster using docker-compose, including the official documentation for Elasticsearch 8.0. However, I cannot find a reason why you would set up multiple nodes on the same docker host. Is this the recommended setup for a production environment? Or is it an example of theory in practice?

...

ANSWER

Answered 2022-Mar-04 at 15:49

You shouldn't consider this a production environment. The guides are examples, often for lab environments, and testing scenarios with the application. I would not consider them production ready, and compose is often not considered a production grade tool since everything it does is to a single docker node, where in production you typically want multiple nodes spread across multiple availability zones.

Does docker-compose support init container?

Asked 2022-Jan-25 at 09:32

init container is a great feature in Kubernetes and I wonder whether docker-compose supports it? it allows me to run some command before launch the main application.

I come cross this PR https://github.com/docker/compose-cli/issues/1499 which mentions to support init container. But I can't find related doc in their reference.

ANSWER

Answered 2021-Dec-21 at 14:11

This was a discovery for me but yes, it is now possible to use init containers with docker-compose since version 1.29 as can be seen in the PR you linked in your question.

Meanwhile, while I write those lines, it seems that this feature has not yet found its way to the documentation

You can define a dependency on an other container with a condition being basically "when that other container has successfully finished its job". This leaves the room to define containers running any kind of script and exit when they are done before an other dependent container is launched.

To illustrate, I crafted an example with a pretty common scenario: spin up a db container, make sure the db is up and initialize its data prior to launching the application container.

Note: initializing the db (at least as far as the official mysql image is concerned) does not require an init container so this example is more an illustration than a rock solid typical workflow.

The complete example is available in a public github repo so I will only show the key points in this answer.

Answered 2021-Dec-21 at 21:47

The issue is that when connecting in a docker-compose network, you have to connect to the hostname of the container, in this case db.

You could also use the other container's IP but would take additional amount of work, it's simpler to just use the hostname.

In other words, you have the wrong connection string, I got this as well when connecting to localhost

QUESTION

AWX all jobs stop processing and hang indefinitely -- why

Asked 2021-Dec-21 at 14:42

Problem

We've had a working Ansible AWX instance running on v5.0.0 for over a year, and suddenly all jobs stop working -- no output is rendered. They will start "running" but hang indefinitely without printing out any logging.

The AWX instance is running in a docker compose container setup as defined here: https://github.com/ansible/awx/blob/5.0.0/INSTALL.md#docker-compose

Observations

Standard troubleshooting such as restarting of containers, host OS, etc. hasn't helped. No configuration changes in either environment.

Upon debugging an actual playbook command, we observe that the command to run a playbook from the UI is like the below:

ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

That's broken down into three commands in sequence:

ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

You can see in part 3, the -vvvvv is the debugging argument -- however, the hang is happening on command #1. Which has nothing to do with ansible or AWX specifically, but it's not going to get us much debugging info.

I tried doing an strace to see what is going on, but for reasons given below, it is pretty difficult to follow what it is actually hanging on. I can provide this output if it might help.

Analysis

So one natural question with command #1 -- what is 'ssh_key_data'?

Well it's what we set up to be the Machine credential in AWX (an SSH key) -- it hasn't changed in a while and it works just fine when used in a direct SSH command. It's also apparently being set up by AWX as a file pipe:

prw------- 1 root root 0 Dec 10 08:29 ssh_key_data

Which starts to explain why it could be potentially hanging (if nothing is being read in from the other side of the pipe).

Running a normal ansible-playbook from command line (and supplying the SSH key in a more normal way) works just fine, so we can still deploy, but only via CLI right now -- it's just AWX that is broken.

Conclusions

So the question then becomes "why now"? And "how to debug"? I have checked the health of awx_postgres, and verified that indeed the Machine credential is present in an expected format (in the main_credential table). I have also verified that can use ssh-agent on the awx_task container without the use of that pipe keyfile. So it really seems to be this piped file that is the problem -- but I haven't been able to glean from any logs where the other side of the pipe (sender) is supposed to be or why they aren't sending the data.

Had the same issue starting this Friday in the same timeframe as you. Turned out that Crowdstrike (falcon sensor) Agent was the culprit. I'm guessing they pushed a definition update that is breaking or blocking fifo pipes. When we stopped the CS agent, AWX started working correctly again, with no issues. See if you are running a similar security product.

How to set Docker Compose `env_file` relative to `.yml` file when multiple `--file` option is used?

Asked 2021-Dec-20 at 18:51

I am trying to set my env_file configuration to be relative to each of the multiple docker-compose.yml file locations instead of relative to the first docker-compose.yml.

The documentation (https://docs.docker.com/compose/compose-file/compose-file-v3/#env_file) suggests this should be possible:

If you have specified a Compose file with docker-compose -f FILE, paths in env_file are relative to the directory that file is in.

ANSWER

Answered 2021-Dec-20 at 18:51

It turns out that there's already an issue and discussion regarding this:

https://github.com/docker/compose/issues/3874

The thread points out that this is the expected behavior and is documented here: https://docs.docker.com/compose/extends/#understanding-multiple-compose-files

When you use multiple configuration files, you must make sure all paths in the files are relative to the base Compose file (the first Compose file specified with -f). This is required because override files need not be valid Compose files. Override files can contain small fragments of configuration. Tracking which fragment of a service is relative to which path is difficult and confusing, so to keep paths easier to understand, all paths must be defined relative to the base file.

There's a workaround within that discussion that works fairly well: https://github.com/docker/compose/issues/3874#issuecomment-470311052

The workaround is to use a ENV var that has a default:

${PROXY:-.}/haproxy/conf:/usr/local/etc/haproxy
