This is an interim solution (in lieu of redesigning the entire IAM permissions infrastructure) that adds finer-grained permissions for the AWS services (s3, ec2, ecr, dynamoDB, etc.).

The permissions were generated by downloading the AWS event history as a csv file and running the following script (converted from a Jupyter notebook):

#!/usr/bin/env python
# coding: utf-8

# In[1]:


import pandas as pd


# In[2]:


df = pd.read_csv("event_history.csv")
df = df[(df["User name"] == "GitHubActions") | (df["User name"] == "[email protected]")]


# In[3]:


df = df[["Event source", "Event name"]]
gb = df.groupby(by=["Event source", "Event name"], as_index=False).count()


# In[4]:


output = gb.apply(lambda r: ":".join((r["Event source"].split(".")[0], r["Event name"])), axis=1)


# In[5]:


output.to_json("permissions_used.json", orient="records")

If the permissions here are not sufficient, an administrator can individually add any that are missing to web/deploy/terraform/modules/iam/policies/gha-policy.json
