# etcd3_wrapper
|
||
|
|
A thin wrapper around Python module [etcd3](https://pypi.org/project/etcd3/) to make it a little easier to deal with etcd.
|
||
|
|
|
||
|
|
**Warning: The API isn't fully stable and can changed significantly in future.**
|
||
|
|
|
||
|
|
For Example, you want to get an entry from etcd.
|
||
|
|
You would write something like this
|
||
|
|
|
||
|
|
```python
|
||
|
|
from etcd3_wrapper import Etcd3Wrapper
|
||
|
|
|
||
|
|
client = Etcd3Wrapper()
|
||
|
|
entry = client.get("/planet/earth")
|
||
|
|
|
||
|
|
if entry:
|
||
|
|
# It would print key and value of entry
|
||
|
|
# in bytes format b'....'
|
||
|
|
print(entry.key, entry.value)
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Output
|
||
|
|
|
||
|
|
```
|
||
|
|
b'/planet/earth' b'{"population": "7.53 Billion"}'
|
||
|
|
```
|
||
|
|
|
||
|
|
```python
|
||
|
|
# If you know that the value in etcd is in JSON
|
||
|
|
# format. You can do the following
|
||
|
|
|
||
|
|
json_entry = client.get("/planet/earth", value_in_json=True)
|
||
|
|
|
||
|
|
if json_entry:
|
||
|
|
# Now, entry.value is of type dict
|
||
|
|
print(entry.key, entry.value)
|
||
|
|
|
||
|
|
# So, you can do this too
|
||
|
|
print(f"Earth population is {entry.value['population']}")
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Output
|
||
|
|
|
||
|
|
```
|
||
|
|
/planet/earth {"population": "7.53 Billion"}
|
||
|
|
Earth population is 7.53 Billion
|
||
|
|
```
